7 FUNCTIONAL DESCRIPTION

7.1 Oscillators

7.1.1 VCO

TheL and Ctuned VCO provides thelocal oscillator signal

for both FM and AM mixer 1. It has a frequency range of

151.2 to 248.2 MHz.

7.1.2 CRYSTAL OSCILLATOR

The crystal oscillator provides a 20.5 MHz signal that is

used for:

•Reference frequency for frequency synthesizer PLL

•Local oscillator for AM mixer 2

•Reference frequency for the IF counter

•Timing signal for the RDS update algorithm

•Reference frequency (75.4 kHz) for the TEA688x (car

audio signal processor - CASP) or TEF689x (car radio

integrated signal processor - CRISP).

7.1.3 PLL

Fast synthesizer PLL tuning system with local control for

inaudible RDS updating.

7.2 FM signal channel

7.2.1 DAA

FM RF Digital Auto Alignment (DAA) circuitry for the

conversion of the VCO tuning voltage to a controlled

alignment voltage for the FM antenna tank circuit.

7.2.2 FM I/Q MIXER

FM quadrature mixer converts FM RF (65 to 162.55 MHz)

to IF of 10.7 MHz. The FM mixer provides inherent image

rejection and high RF sensitivity.

It is capable of tuning the US FM, US weather,

Europe FM, Japan FM and East Europe FM bands:

•US FM = 87.9 to 107.9 MHz

•US weather FM = 162.4 to 162.55 MHz

•Europe FM = 87.5 to 108 MHz

•Japan FM = 76.0 to 91 MHz

•East Europe FM = 65.8 to 74 MHz.

7.2.3 FM KEYED AGC

FM contains keyed wide-band RF AGC. AGC detection

occursattheFM mixer.Thewide-bandRF signalswitches

a narrow band signal (IF) from the FM IF level detector

circuitry that controls the FM RF AGC block.

It includes an AGC PIN diode drive circuit for the FM RF

AGC.The PIN diode drive can be activated via theI2C-bus

as a local or distance function.

The AGC threshold is programmable and the keyed AGC

function is switchable via the I2C-bus.

7.2.4 FM IF AMPLIFIERS

The two FM IF amplifiers provide 10 dB and 4 dB

amplification with high linearity and dynamic range.

7.2.5 FM DEMODULATOR

The FM quadrature demodulator includes automatic

centre frequency adjustment and THD compensation.

7.3 AM signal channel

7.3.1 AM TUNER INCLUDING MIXER 1AND MIXER 2

The AM tuner is realized in a double conversion technique

and is capable of selecting LW, MW and SW bands.

AM mixer 1 converts AM RF to IF1 of 10.7 MHz, while

AM mixer 2 converts IF1 of 10.7 MHz to IF2 of 450 kHz:

•LW = 144 to 288 kHz

•MW = 530 to 1710 kHz (US AM band)

•SW = 5.85 to 9.99 MHz (including the 31 m, 41 m and

49 m bands).

7.3.2 AM RF AGC AND IF2 AGC

The AM RF includes a PIN diode drive circuit. The

threshold detection points for AM AGC are performed at

AM mixer 1 and AM IF2. AGC thresholds are

programmable via the I2C-bus.

7.3.3 AM DETECTOR

The AM detector provides AM level information and

AM AF or AM IF2.

7.3.4 AM AF OR IF2 SWITCH

The AM output provides either a detected AM AF or the

corresponding AM IF2 signal. The IF2 signal can be used

for AM stereo decoder processing.

value at pin AMNBHOLD.

7.3.6 FM AND AM LEVEL DETECTOR

FM and AM level detectors provide the temperature

compensated output voltage. The starting points and

slopes of the level detector outputs are programmable via

the I2C-bus.

7.4 Test mode

The test mode of the IC is activated by:

•Sending the test byte (byte 5) to the IC

•Connecting pin FREF through a 100 kΩ resistor to

VDDA1

•Applying 50 µA to pin FREF.

If the test mode is enabled by pin FREF:

•The settling time of the AM IF2 AGC is reduced to less

than 100 ms in the nominal application

•The digital-to-analog converters for the antenna DAA

and the level DAA can be clocked directly by the SCL

line of the I2C-bus

•The output at pin FREF can be selected by the I2C-bus:

TEA688x or TEF689x reference frequency, PLL

reference frequency or PLL programmable divider

output frequency

•The RDS update control circuit can be clocked directly

via pin DAATD

•Pin T1AMAGC can be used to enable the load PLL

circuit of the RDS update control circuit

•Charge pumps can be set into 3-state mode.

8 LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 60134).

Notes

1. To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any

5 V supply voltage. This is also necessary during power-on and power-down sequences. Precautions have to be

provided in such a way that interferences can not pull down the 8.5 V supply below the 5 V supply.

2. Machine model (R = 0 Ω, C = 200 pF).

3. Human body model (R = 1.5 kΩ, C = 100 pF).

12 I2C-BUS PROTOCOL

12.1 I2C-bus speciﬁcation

Informationabout theI2C-buscanbefound inthebrochure

“The I

C-bus and how to use it”

(order number

9398 393 40011).

The standard I2C-bus specification is expanded by the

following definitions.

IC addresses:

•1st IC address C2: 1100001

•2nd IC address C0: 1100000.

Structure of the I2C-bus logic: slave transceiver with auto

increment.

Subaddresses are not used.

Exception to the standard I2C-bus specification:

•The data hold time tHD;DAT must be at least 1 µs.

12.1.1 TEST MODE

Connecting pin FREF to VDDA1 via a 100 kΩ resistor or

feeding 50 µA into that pin switches the IC into the test

mode.

During test mode the digital-to-analog converters of the

leveland antenna DAA functionscan be sequencedby the

I2C-bus SCL line.

During test mode either the TEA688x or TEF689x

reference frequency, the PLL reference frequency divider

or the programmable divider output can be switched to

pin FREF.

12.1.2 DATA TRANSFER

Data sequence: address, byte 1, byte 2, byte 3, byte 4,

byte 5, and byte 6. The data transfer has to be in this

order. The LSB = 0 indicates a WRITE operation to the

TEA6846H.

Bit 7 of each byte is considered the MSB and has to be

transferred as the first bit of the byte.

The data becomes valid at the output of the internal

latches with the acknowledge of each byte. A STOP

condition after any byte can shorten transmission times.

When writing to the transceiver by using the STOP

condition before completion of the whole transfer:

•The remaining bytes will contain the old information

•If the transfer of a byte is not completed, this byte is lost

and the previous information is available.

In byte 5, 4 bits are reserved for test mode purposes.

Those can only be used when the test mode is activated

by the select pin FREF.

12.1.3 I2C-BUS PULL-UP RESISTORS

When the IC is used together with the TEA688x or

TEF689x and both SCL and SDA lines are connected via

the I2C-bus to the TEA688x or TEF689x, the pull-up

resistors of the tuner IC should be connected to the digital

supply voltage of the TEA688x or TEF689x. Otherwise an

I2C-bus pull-down can occur switching off the tuner IC

supply when the I2C-bus buffer interface of the TEA688x

or TEF689x is enabled for data transfer to the tuner IC.

12.1.4 FREQUENCY SETTING

For new frequency setting, in both AM and FM mode, the

programmable divider is enabled by setting bit MUTE = 1.

To select an FM frequency, two I2C-bus transmissions are

necessary:

•First: bit MUTE = 1

•Second: bit MUTE = 0.

15 SOLDERING

15.1 Introduction to soldering surface mount

packages

Thistextgivesaverybriefinsighttoacomplextechnology.

A more in-depth account of soldering ICs can be found in

our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).

There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for

certainsurface mount ICs, but it isnotsuitableforfinepitch

SMDs. In these situations reflow soldering is

recommended.

15.2 Reﬂow soldering

Reflow soldering requires solder paste (a suspension of

fine solder particles, flux and binding agent) to be applied

totheprinted-circuit board byscreenprinting, stencilling or

pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,

convection or convection/infrared heating in a conveyor

type oven. Throughput times (preheating, soldering and

cooling) vary between 100 and 200 seconds depending

on heating method.

Typical reflow peak temperatures range from

215 to 250 °C. The top-surface temperature of the

packages should preferable be kept below 220 °C for

thick/large packages, and below 235 °C for small/thin

packages.

15.3 Wave soldering

Conventional single wave soldering is not recommended

forsurface mount devices (SMDs) or printed-circuit boards

with a high component density, as solder bridging and

non-wetting can present major problems.

To overcome these problems the double-wave soldering

method was specifically developed.

If wave soldering is used the following conditions must be

observed for optimal results:

•Use a double-wave soldering method comprising a

turbulent wave with high upward pressure followed by a

smooth laminar wave.

•For packages with leads on two sides and a pitch (e):

– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the

transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the

printed-circuit board.

The footprint must incorporate solder thieves at the

downstream end.

•Forpackageswith leads on foursides,thefootprintmust

be placed at a 45°angle to the transport direction of the

printed-circuit board. The footprint must incorporate

solder thieves downstream and at the side corners.

During placement and before soldering, the package must

be fixed with a droplet of adhesive. The adhesive can be

applied by screen printing, pin transfer or syringe

dispensing. The package can be soldered after the

adhesive is cured.

Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal

of corrosive residues in most applications.

15.4 Manual soldering

Fix the component by first soldering two

diagonally-opposite end leads. Use a low voltage (24 V or

less) soldering iron applied to the flat part of the lead.

Contact time must be limited to 10 seconds at up to

300 °C.

When using a dedicated tool, all other leads can be

soldered in one operation within 2 to 5 seconds between

270 and 320 °C.

15.5 Suitability of surface mount IC packages for wave and reﬂow soldering methods

Notes

1. Formoredetailed information on theBGApackagesrefer to the

“(LF)BGAApplicationNote

”(AN01026);ordera copy

from your Philips Semiconductors sales office.

2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum

temperature (with respect to time) and body size of the package, there is a risk that internal or external package

cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the

Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder

cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,

the solder might be deposited on the heatsink surface.

4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.

The package footprint must incorporate solder thieves downstream and at the side corners.

5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not

suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

6. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is

definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
