INTRODUCTION

1) Dolby is a registered trademark

of the Dolby Labs Licensing

Corporation, San Francisco, CA,

USA.

The last few years have seen a

revolution in the popularity of

portable and home audio

equipment. It’s a revolution

brought about by a greater choice

of equipment for the consumer,

ranging from pocket-sized radios

and personal hi-fi to top quality

music centres, at a price to suit all

pockets. And it’s almost entirely

due to increased integration of

electronic components and smaller

packaging. This revolution is, of

course, self-perpetuating: the

enormous number of FM stereo

stations that can now be received,

and the availability of cassettes &

CDs, has spurred on the

production of even higher

performance portable and

domestic radio/audio with more

features.

For the semiconductor

manufacturer, minimizing the

number of peripheral circuit

components is the norm, thus

improving quality and reliability,

and reducing the overall

equipment size and cost. However

integrating radio receivers

presents its own special problems;

overcrowded wavebands, small

aerials and close proximity of

components all increase the

chances of interference. By fully

exploiting the experience gained

from our close relationship with

radio setmakers, and combining it

with our unrivalled experience of

developing ICs using advanced

circuit techniques, we’ve

developed our present

comprehensive range of

completely-integrated radio

systems that does more and

performs better than ever before.

Our range comprises ICs and

discrete semiconductors for

portable radios, mains-powered

radios including Digital Satellite

Broadcast (DSB) receivers, and

radios for multimedia PCs. All are

optimized for performance

(distortion, sensitivity, etc.),

minimum peripheral components

and adjustments, and the best

possible reception.

For miniature ‘credit-card’ or

pocket-sized radios, we have an

AM mono receiver IC that

operates froma3Vbattery with

minimum power consumption and

requires very few peripheral

components. This IC overcomes

the difficulty of providing manual

tuning for such a small radio by

incorporating a simple search

tuning facility operated by two

push-buttons.

For personal radios, clock

radios, portable radios and

portable radio-recorders, we offer

a variety of highly-integrated

two-chip manually-tuned AM/FM

configurations; for mono and

stereo reception. We also have an

AM/FM stereo configuration that is

optimized for use with a computer-

controlled PLL frequency

synthesizer for digital tuning. All

these ICs operate from as little as

2 V or up to 18 V with minimum

power consumption and require

very few, if any, peripheral

components. This minimizes costs

and simplifies design.

The latest addition to our range

of radio ICs is an innovative

computer-controlled AM/FM

Self-Tuned Radio (STR) which

operates from a 2.2 V to 12 V

supply. This single-chip self-tuned

radio performs all the functions

from the aerial input to the stereo

decoder outputs. The tuning

concept used in the STR

combines the advantages of

manual tuning with electronic

tuning facilities and features. The

inherent fuzzy logic behaviour of

the STR mimics manual tuning

(coarse tuning followed by fine

tuning) and achieves fast and

reliable tuning to the desired

frequency.

The performance, flexibility and

wide supply voltage range of our

ICs for personal radios and

portables also allows them to be

combined with other ICs from our

radio/audio range to form chipsets

for all performance classes of

mains-powered stereo FM, MW

and LW hi-fi tuners mini/midi

systems and music centres. ICs

that can be added include a PLL

frequency synthesizer plus

microcontroller for electronic

tuning and control, source

selector, tone/volume/balance

control circuits, power amplifiers,

CD player ICs, Dolby1) B/C noise

reduction circuits for cassette

recorders, and remote control ICs.

And with the advent of

multimedia systems we offer a

range of radio PC cards based

around the OM56xx family of

tuners. These radio PC cards offer

full R(B)DS capabilities and are

fully shielded against the extreme

electrical noise found within a PC

to deliver clear, hi-fi quality FM

stereo radio signals in a

multimedia system.

POCKET-SIZED RADIO

(TEA5551T)

The TEA5551T is a complete AM

radio IC incorporating a dual AF

amplifier with low quiescent

current. It is primarily designed for

pocket radios operating from a

3 V supply (maximum output

power is with a 4.5 V supply, with

a power output of 2 ×60 mW

when used with 32 Ωheadphones

or 100 mW in bridge-tied load

(BTL) with a 50 Ωloudspeaker).

This IC has an AF part with low

radiation (HF noise) and good

overdrive performance.

Features

RADIO (TDA7088T +

TDA7050T)

The TDA7088T is the latest of our

single-chip FM receivers for

pocket radios. Previous single-chip

receivers have used trim-capacitor

tuning systems which meant using

a very small tuning knob to cover

the whole FM band. The

TDA7088T overcomes this by

incorporating a simple search

tuning facility which can be

operated by two push buttons.

The TDA7088T contains all

stages needed for FM reception.

Operation is based on a

Frequency-Locked Loop (FLL)

system with conversion to an IF of

75 kHz. We recommend using this

receiver in conjunction with the

TDA7050T (or the TDA7052)

audio amplifier.

RADIO (TEA5710(T) +

TDA7052/52A/52B)

The TEA5710(T) is an AM/FM

receiver IC for use in clock radios,

portable radios, mains-fed radios

and medium-fi sets. It incorporates

all circuitry from the AM/FM front-

end to the detector outputs. Only

a minimum number of external

components are required to

complete a radio set. We

recommend using it with the

TDA7052 or TDA7052A/52B

amplifier.

The TEA5710(T) has many

features such as distributed

selectivity on both AM and FM,

and a symmetrical AFC for tuning.

The distributed IF gain allows a

simple PCB layout. A new aspect

in AM reception is the high

impedance AM RF input made by

a differential MOST pair. This

enables connection to the top of

the input selectivity (e.g. the

ferroceptor) which simplifies radio

design and reduces the number of

necessary contacts.

TEA5710(T) Features

wide supply voltage range

low current consumption

high selectivity with distributed

IF gain

LED driver for tuning indication

high input sensitivity

good strong-signal behaviour

low output distortion

designed for simple and reliable

PCB layout

high impedance MOSFET input

on AM.

Amplifiers

The A and B versions differ from

the TDA7052 in that they have a

DC volume control with mute

mode.

12(T) + TDA7053(A)A/57(A)Q)

For a portable stereo radio, we

offer a variety of two-chip

solutions, depending on your

performance requirements. The

TDA7057Q/57AQ amplifiers offer

outputs as high as3Wper

channel while the TDA7053/53A

offer 1.2 W per channel. All ICs

can operate froma3to12V

supply and require no peripheral

components.

Both the TEA5711 and

TEA5712 receiver ICs differ from

the TEA5710 in that they include

a stereo decoder. Principally, their

applications include portable

radios, Mini/Midi receiver sets and

RADIO (TDA7021T +

TDA7040T + TDA7050T)

The TDA7021T stereo FM

receiver circuit is for

pocket-sized radios and is fully

compatible with applications using

the low-voltage micro tuning

system (MTS).

The IC has a frequency locked

loop (FLL) system with

intermediate frequency of 76 kHz.

The selectivity is obtained by

active RC filters.

Because of the low-pass

characteristics of the FLL, a

50 kHz roll-off compensation is

performed by the integral LF

amplifier. For mono applications,

this amplifier can be used to drive

an earphone. The field-strength

detector enables field-strength

dependent channel separation

control. We recommend using this

receiver in conjunction with the

TDA7040T PLL stereo decoder

and the TDA7050T stereo audio

amplifier.

TUNERS (OM5604/06/08)

The OM5604, OM5606 and

OM5608 FM tuner modules are

designed to operate in the harsh

electrical environment of the PC

and deliver clear, hi-fi quality

stereo radio signals in a

multimedia system. The modules

are fully shield for the PC

environment and offer MPX output

for Radio (Broadcast) Data

Systems (R(B)DS) decoding. Both

modules have an 75 ΩRF aerial

input (the OM5604 has an

F-connector and the OM5606 and

an IEC-connector).

The OM5604/06 modules

comprise three ICs: the

TEA5757H, the PCF8574T and

the TDA1308T.

The TEA5757H self-tuned radio

(STR) FM receiver lies at the

heart of the modules. It is an FM

receiver, stereo decoder and

tuning synthesizer on one chip.

After searching for the desired

channel, it automatically locks

onto the signal for the best

possible reception. If the receiver

is tuned to a strong local

transmission, local/DX switching

ensures reception is not

overpowered.

More details on the TEA5757H

STR are given in the section

Self-

tuned AM/FM radio IC.

The PCF8574T is a bus

converter that provides I2C-bus

control and has three I/O lines for

additional control functions. The

TDA1308T is a line amplifier with

two line outputs.

Fig.13 RDS demodulator (SAA6579T)

RDS system

This demodulator & decoder

system is based around two ICs:

the SAA6579T RDS demodulator

and the CCR910, CCR911,

CCR912 or CCR921 RDS

decoder. These ICs recover the

bi-phase inaudible

frequency/programme information

which is serially transmitted with

FM radio broadcasts that use the

Radio Data System (RDS).

The information is converted

into data for controlling the tuning/

display functions of the radio via

the I2C-bus and the main

microcontroller of the radio.

In the RDS demodulator, the

RDS signal is separated from the

MPX signal by a 57 kHz bandpass

filter, and digitized using a

comparator. The digitized signal is

then synchronously demodulated

to recover the bi-phase data

symbols. For this function, the

suppressed 57 kHz subcarrier is

regenerated by a special PLL

system (Costas loop). The

demodulated data symbols are

further processed in an integrate

and dump circuit followed by a

differential decoder which

generates the RDS data (RDDA)

signal. The bit rate RDS clock

(RDCL) is recovered by a second

PLL. The integrate and dump

circuit also generates a quality

signal (QUAL) for every data bit.

The RDS decoder is an 80C51

family microcontroller with

intelligent RDS data decoding and/

or pre-processing software. The

software incorporates automatic

error detection/correction. A

subset of the decoded RDS data

is present within the serial

interface protocol and also made

available on the pins of the

decoder IC.

RDS/RBDS system

This is similar to the RDS system

described above, except a

CCR921 R(B)DS decoder is used.

The CCR921 supports all types

of R(B)DS groups and is easy to

use via the I2C-bus interface.

Furthermore, as the timing

requirements of the (main-) set

controller of the R(B)DS data

processing are reduced, radio

control software can be developed

specifically for radio features.

RADIO RECEIVER ICs

The TEA5710(T), TEA5711(T) and

TEA5712(T) are all high-

performance, BiCMOS ICs for use

in portable AM/FM radios. All

necessary functions are

integrated, from the AM & FM

front end to the detector output

stages, to make a complete radio.

The TEA5710(T) design has

new features to improve

performance and tuning behaviour.

Performance features include

distributed selectivity on both AM

and FM, and minimal variation

with supply voltage. Tuning is

improved by using a symmetrical

AFC. The distributed IF gain

allows a simple PCB layout.

Furthermore, the AM/FM inputs

and the varicon are referred to

ground. A new aspect in AM

reception is the high impedance

AM RF input made by a

differential MOST pair. This

enables connection to the top of

the input selectivity (e.g. the

ferroceptor) which simplifies radio

design and reduces the number of

necessary switches in multiband

radios.

The TEA5711(T) and

TEA5712(T) have all the features

of the TEA5710(T). In addition,

they also have a built-in stereo

decoder with stereo blend

controlled by field strength. They

also feature a soft mute to

suppress inter-station noise.

The TEA5712(T) differs from

the TEA5711(T) in that it is

optimized for digital tuning

systems: the AM/FM IF output

signal is available for IF counting.

Common features

wide supply voltage range

low current consumption

high selectivity with distributed

IF gain

high input sensitivity

good strong-signal behaviour

(10 V/m AM, 500 mV FM)

low output distortion

simple, reliable PCB layout

RADIO IC

The TEA5757H IC is single-chip,

self-tuned radio (STR). It contains

a complete AM/FM receiver,

stereo decoder, self-tuning VCO,

stop circuitry and bus interface.

As such it perform all the

functions from the aerial input to

the stereo decoder outputs. The

tuning concept used in the IC

combines the advantages of

manual tuning with the facilities

and features associated with

electronic tuning. This is because

of the inherent fuzzy logic

behaviour of the STR which

mimics manual tuning (course

tuning followed by fine tuning) and

achieves fast and reliable tuning

to the desired frequency.

The STR searches for strong

signals and allocates them to

preset channels, typically

identifying 40 stations within just

20 seconds. When the station is

selected the signal is locked and

the IC goes into a standby mode.

If at any time the quality of the

signal weakens, the chip “wakes

up” and fine-tunes itself again.

Also, local/DX switching ensures

reception is not overpowered

when tuned to a strong local

transmitter.

CONTROL AND DISPLAY

Over the years, the continually

expanding range of Philips’ ICs for

radio and audio has allowed set

manufacturers to implement

remote control and extend

microcomputer control to virtually

all the functions of a radio and hi-

fi system. This has led to

incorporation of many new

facilities such as electronic tuning

with search facilities, preset

station selection, digital frequency

indication and operation in

conjunction with Radio Data

System (RDS) information.

Microprocessor control

To assist audio equipment

manufacturers incorporate

computer control into their circuit

designs, Philips supply one of the

widest available ranges of 8-bit

CMOS microcontroller derivatives.

All are based on the industry

standard 8051, with architectural

enhancements that make them

suitable for radio and hi-fi control

systems. They all include an

80C51 CPU, use the 80C51

instruction set, and have a wide

variety of on-chip peripheral

functions; expansion of I/O lines,

A to D conversion, I2C-bus

interface, expanded program ROM

and data RAM, watchdog timer,

UART, 16-bit timer/event counters,

and on-chip oscillator and timing

circuits.

Our microcontrollers are

supported by a range of 1K to 8K

CMOS static EEPROMs. Most of

these non-volatile memories have

an I2C-bus interface and unique

Philips’ circuitry for improving

reliability by correcting single-bit

failures.

Display drivers

To simplify the user interface of

hi-fi equipment, it is necessary to

have a multitude of parameters

displayed by LCD segments.

Examples of such displays are

tuning information, analog control

settings, RDS/RBDS functions, CD

and tape information etc.

Philips’ extensive range of I2C-

bus controlled LCD drivers are

ideal for driving LCD segments or

dot-matrix LCD graphics panels

either directly or at multiplex rates

up to 1:4 (segment displays) or

1:32 (dot-matrix displays).

CIRCUITS

In the past, insufficient command

capacity of remote controllers and

non-standardization of commands

and protocols made it impossible

to operate all remotely controlled

equipment from a single remote-

control handset. To solve this

problem, Philips has developed a

remote control protocol (RC-5)

and the ICs to support it.

The RC-5 protocol provides

unified remote control of consumer

equipment. It can handle up to

4096 commands organized as two

sets of 64 commands in 32

individually addressable groups,

each of which can be allocated to

a separate unit or system. Since

many of the 128 commands can

control the same function in each

different pieces of equipment (e.g.

a tuner or an amplifier), RC-5

allows a single remote control

handset with relatively few keys to

control any individual item of

equipment or an entire integrated

system. Obviously, to ensure that

there are no spurious responses

to commands given to items of

equipment from different

manufacturers, it is essential to

have some degree of

standardization in the allocation of

system addresses and command

codes. This standardization, and a

procedure for the allocation of new

or additional codes, already exists

within Philips and is available to

our customers.

Remote control system

architecture

The remote control system

consists of an infrared transmitter,

a receiver, and decoding software

in the central microcontroller of the

equipment being controlled.

The transmitter is a dedicated

PCA84CX22 microcontroller for

the required digital data output. A

biphase-coded bitstream

modulates a 36 kHz carrier which

is subsequently converted into an

infrared signal by an IR LED.

At the receiving end, the

infrared signal from the transmitter

is detected, demodulated,

amplified and filtered.

If local control is required,

amplified output from the keyboard

scanner is passed directly to the

central microcontroller of the

equipment for decoding.

PCA84CX22 - remote control

transmitters

Philips’ PCA84CX22 family of

transmitters are dedicated low-

voltage, stand-alone 8-bit

microcontrollers that can be mask-

programmed to generate the

control command codes in

accordance with the RC-5 protocol

or any other protocol of a set

manufacture’s choice. Each

contains an 84CXXX CPU with

ROM, RAM and the following

additional on-chip peripherals:

interrupt gate

modulator for providing

adjustable pulse bursts, pulse

duration and pulse duty factor

watchdog timer to prevent

malfunction or the transmitter

being locked

8-bit programmable timer/event

counter with 5-bit prescaler

1 Mhz to 6 Mhz oscillator.

Input/output expanders

We also have two I/O expanders

to complement our remote control

ICs - the PCF8574(A) and the

SAA130. These two ICs provide

remote I/O expansion for most

microcontrollers via the I2C-bus.

and frequency) of loud

components. This phenomenon is

called masking.

Layers I and II of ISO/MPEG-1

reduce the data by splitting the

broadband audio source signal

into 32 sub-bands of equal width.

The masking threshold (the

amount of imperceptible audio

energy as a function of frequency)

is determined for the given signal

by using the psycho-acoustic

model. The sub-band samples are

then re-quantized to an accuracy

that ensures that the spectral

distribution of the re-quantization

noise does not exceed the

masking threshold. This reduction

of representation accuracy

provides the reduction of the audio

data. The re-quantized sub-band

samples are multiplexed with side

information concerning the actual

re-quantization to form the MPEG

audio bitstream.

During decoding, the MPEG

audio bitstream is de-multiplexed

and the side information is used to

reconstruct the sub-band signals

which are combined to form a

broadband audio output signal.

We have two MPEG audio

decoders suitable for hi-fi systems:

a Digital audio broadcast decoder

(SAA2501H) and an MPEG-1/2-

compatible audio decoder

(SAA2502H).

Depending on features (see

below), both products are ideally

suited for use in ADR and DAB

receivers.

specific 4-channel DSP for audio

signals. In the general mode, it

can provide listening environment

enhancements such as

equalization, concert hall-effects,

reverberation, surround sound/

karaoke processing, and digital

volume/balance control.

In the dual/quad filter modes,

the IC can also be reconfigured as

a dual or quad digital filter with

programmable frequency

characteristics.

A stereo expansion mode

provides stereo digital filtering,

5-band graphic equalization and

complex stereo expansion for

headphone out-of-head and

incredible stereo applications.

Bitstream/CC filter-DACs

These filter-DACs feature a unique

combination of bitstream and

continuous calibration techniques.

The DAC functions as a bitstream

converter for low-level signals, and

as a dynamic continuous

calibration converter for large

signals. This technique results in

low power consumption, a small

chip and simple application.

These DACs include up-

sampling filtering and noise-

shaping. The combination of high

oversampling up to 16fs, second-

order noise-shaping and

continuous calibration ensures that

only simple 1st-order analog post-

filtering is required.

These DACs accept input in I2S

format or Japanese format with

word lengths of 16, 18 and 20

bits. Four cascaded filters

increase the oversampling rate to

×16. A sample-and-hold function

increases the oversampling rate in

normal speed mode to ×96

(fsys = 384fs)or×128 (fsys = 256fs)

or to ×48 (fsys = 256fs)or×64

(fsys = 384fs). A 2nd-order noise

shaper converts this oversampled

data into a bitstream.

The DACs incorporate special

data encoding. This ensures an

extremely high signal-to-noise

ratio, superior dynamic range, and

immunity to process variations and

component ageing.

Two on-chip operational

amplifiers convert the DAC output

currents into voltages. Externally-

connected capacitors perform the

required 1st-order post filtering.

No further filtering is required.

The unique combination of

bitstream and continuous-

calibration techniques, together

with a high degree of analog and

digital integration, results in a

single-filter DAC with 18-bit

dynamic range, high linearity, and

simple, low-cost application.

Philips’ audio control ICs

incorporate stereo pairs of

resistive voltage dividers

connected to multi-input op-amps,

the tail currents of which are

either DC controlled via

potentiometers, or digitally

controlled via the I2C-bus to adjust

volume level, stereo balance, bass

level, treble level and fader/output

selection. The advantages of this

principle are very wide dynamic

range combined with low noise

and distortion. The low noise and

low distortion figures have resulted

in approval for use with cassette

players with Dolby B and C noise

reduction.

Some of the ICs include a

fader control which is independent

of the volume control which

permits sound distribution

adjustment between two pairs of

audio power amplifiers. And some

include a source selector (e.g. for

FM, AM or cassette player inputs).

Fig.33 The TEA6360(T) 5-band stereo equalizer

I2C-bus control

The TEA6360(T) is a highly-

integrated 5-band stereo equalizer

with an I2C-bus controlled tone

processor for music centres and

car radio. It incorporates 5 stereo

pairs of constant-bandwidth boost/

cut bandpass filter sections, each

centred on a different audio

frequency. It also has a built-in

I2C-bus interface for receiving filter

setting commands from a

microcontroller. Each stereo pair

of filters has a linear frequency

response setting and can be

simultaneously controlled in 5

steps of centre frequency boost or

cut. The IC is optimized for a

frequency boost/cut of 12 dB in

five 2.4 dB steps. The frequency

response of the filters can be

controlled with constant or variable

Q-factor.

Each filter section consists of a

bridged-T RC network (notch filter)

connected in the input or feedback

path of an internal operational

amplifier. To allow free choice of

the centre frequency, maximum

gain and Q-factor, the reactive

components of each filter section

(2 capacitors and one resistor) are

external. These can be standard

surface-mount types.

In the complete equalizer, 5

filter sections are directly

connected in series for each

stereo channel. Since the overall

DC gain of the circuit is 0 dB

irrespective of the filter settings,

offset voltages are not amplified.

Because the entire circuit is DC-

coupled, has a wide input signal

swing (2.1 V to VS-1V)anda

typical offset of zero, components

for DC decoupling and reference

voltages are not necessary.

CUSTOMER SUPPORT

During the more than twenty years

that Philips has been supplying

ICs to meet the needs of radio/

audio manufacturers, we’ve built

an unrivalled reputation for

keeping our customers at the fore-

front of circuit design and innova-

tion. This reputation wasn’t earned

solely by providing integrated

circuits to meet the industry’s

needs, but also by offering

extensive applications and design-

in support in many countries.

An important part of our

customer support package is our

comprehensive and regularly

updated descriptive publications

and data handbooks.

Another important item is an

IICRADIO I2C-bus control program

(available on 3.5 inch disk). This

program allows engineers to

evaluate, analyze and test Philips’

radio/audio ICs which have an

I2C-bus interface, without

knowledge of the internal software

structure of the circuits.

All that’s needed to run the

program is an IBM or compatible

PC with MS-DOS or PC-DOS and

at least 1 Mb of RAM. An I2C-bus

interface board must be connected

between the I2C-bus of the board

under test and the CENTRONICS

parallel printer port of the PC.

The program incorporates a

database for IC control data and a

set of easy to use dedicated or

universal menus for controlling the

ICs. All the menus are self-

explanatory and the desired

functions can be accessed with a

single keystroke. The dedicated

menus show all the control func-

tions of the associated IC divided

into logical groups. All data

communication on the I2C-bus is

subjected to error checking and, if

errors occur, they’re displayed on

the PC screen as simple, easily

understood messages.
