10 Steps to Better Audio10 Steps to Better Audio

10 Steps to Better Audio

1 Look (and Listen)

beyond the numbers.

SNR, THD+N and sample rate provide a reasonable start

when selecting components to power your design. However

great audio is not about numbers on a sheet of paper, it is

about sound quality and listening experience. Listen to any

AKM DAC, codec or ADC and we’ll bet that you’ll love our

sound over the sound of competing products!

3 Good sound is a system,

not a component. Look at

ALL of the costs.

Some audio converters have low jitter tolerance, requiring extra

money spent in clock circuits to maintain performance. AKM has

some of the best jitter

tolerance in the

business, so consistent,

great performance is

assured.

Competing parts

require more complex

filters or conversion

from a current output

to a voltage output.

AKM DACs are voltage

output devices,

simplifying

external circuitry.

AKM’s superior out-

of-band noise

performance

eliminates complex

multi-pole filters,

relying instead on

simple one or two-

pole designs.

2 Good PCB layout is

crucial to great audio.

The high-frequency clocks used in digital systems (CPU/system

clocks, memory clocks, etc.) can cause problems in the analog

audio domain. Separate ground and power planes, short power

traces and judicious routing of clock signals all play a part in

getting the best performance from your design. If you have any

questions, AKM Application Engineers are happy to review

your design and help you find problem areas. Here are a few

pointers to help you get started with AKM audio:

 Isolate the analog and digital ground planes.

 Place small bypass capacitors as close to the chip as

possible

 Do not place inductors in the power supply lines, as

these restrict the flow of current to the chip and can

reduce performance.

4 Group Delay Deviation: It’s

a Phase Issue.

Group delay deviation relates to how a chip’s architecture affects

signals that travel through it. Group delay deviation comes from

using less-expensive IIR filters on the inputs and outputs of the ADC

or DAC’s internal architecture. These filters cause frequency

dependent time/phase shifts. This means that a 1 KHz sine wave will

go through the device faster than a 5KHz signal, resulting in a phase

shift between these signals.

In multichannel audio, the phase relationship of different frequen-

cies is crucial in providing spatial cues. AKM DACs and A/D convert-

ers use phase-accurate FIR filters. This means that they respond

predictably and accurately, regardless of input frequency or sample

rate. The end result is better sound, better imaging and superior

performance.

Page 5

and Analog Worlds

8 Does your ADC

go to 11?

Well, ours do (sort of). You see, when you saturate the inputs on

any of our A/D converters, the digital output is “pegged” at

maximum value, no mater how much you exceed the input

maximums. Some parts “wrap around” to negative full-scale

(ouch!) and begin re-incrementing. This forces a system designer

to have to compensate for this wrap around either with an

expensive input circuit or through DSP/CPU programming. AKM’s

approach is simple, valid and predicable in its behavior.)

6 Look past 20KHz

response when

evaluating sample rates.

What’s the point of supporting high sample rates if you are only

looking at energy from 20Hz to 20KHz. Instruments like cymbals

and horns have harmonic content well past 20KHz. When you test

audio parts at high sample rates, get rid of AES17 and A-weighted

filters and see what is now happening “in-band”. The lack of noise

in this extended audio band will provide a complete picture of

AKM’s audio excellence!

7 Watch Your Power

Supply.

Noise is a performance killer. Make sure that your power supply is

clean and strong. This will improve audio performance through-

out your system. If possible, use high-quality dedicated regulators

with low ESR (converters need fast access to current) and high

PSRR (Power Supply Rejection Ratio). Your ears will be happier if

you do, and your product’s performance will be at its best.

5 Consistent performance

across all sample

rates.

Filters should scale with sampling frequency. Period. If you are

using low sample rates, like 8KHz or 16KHz, non-scaling filters

place extra noise in the audio spectrum. This reduces performance

or requires the designer to switch between external filters. All

AKM DACs and ADCs feature switched-capacitor technology,

allowing the on-chip analog filters to scale with sample rate. This

reduces external circuitry and ensures superior sound.

A 16K sine wave was sent to the device under test using an Audio Precision System 2

Cascade. The digital output of the board was connected to an AES digital input on a

PC sound card. For five minutes, the AES digital input was recorded using CoolEdit

Pr o. After the data was collected, a digital FFT filter or digital notch filter at 16kHz

was applied. The resultant spikes in the graph show non-linearity or sparkle codes

caused by the errant data.

9 Silence is golden,

get rid of the noise.

Spurious noises. Sparkle codes. Spikes. Non-linearity. Periodic

aberattions. Call it what you will. Whether a converter is

converting or not, unwanted tones are unacceptable. With AKM,

the only time you’ll see (or hear) these objectionable signals is,

well, never. Instead you’ll see a truly random noise floor without

specific tones or spikes. This is the result of superior technology

and careful design. With AKM, you’ll crank up the signal and cut

out the noise.

Use AKM for all of

your audio designs.

D/A converters. A/D converters. S/PDIF. Codecs. AES-EBU.

Sample-rate converters. Class D amplifiers. Performance. Value.

When it comes to audio, make AKM your first stop. No one offers

the breadth of products, the integration, or the support that AKM

offers.

ADC Filters

Now that high-fidelity

sample rates have risen to

192KHz, the internal filters

in analog-to-digital convert-

ers have become much more

complicated. There are two

opinions surrounding the

new 100KHz of passband;

one attempts to record as

much information in this

passband as possible, the

other is to care about

frequencies from 20Hz-

20KHz. AKM filters allow

you to have a flat noise floor

to Fs/2 even when sampling

at 192KHz. The images on

the left illustrate AKM’s

scaling filter versus a part

that fails to scale properly.

AKM gets rid of the noise

and delivers the best sound

along with the widest

bandwidth. Always!

AKM’s DACs feature the

industry’s best integrated

digital filter. This Extraordi-

nary Digital Filter, or EDFTM,

is the result of years of

experience in both electrical

and process engineering.

This filter, combined with

AKM’s superior noise-

shaping techniques, results

in DACs that outperform the

competition by a wide

margin. The plot on the left

shows the difference

between an “ordinary” DAC

(green plot) and AKM’s

reduces design time and cost

while providing outstanding

sound. In fact, our AK5365

ALC

Automatic Level Control

(ALC) is found on many AKM

codecs and ADCs. The ALC is

located between the analog

mic preamp and the ADC

and maintains the incoming

signal at a constant level.

AKM’s ALC provides control

of Level, Time, Step and

Attenuation. Level is a

threshold value above which

the ALC is initiated. Time is

the amount of time that a

signal must spend above the

threshold before ALC starts.

Step allows you to instanta-

neously “step” the clipped

value down by the Attenua-

tion value or to wait until a

zero-crossing point is

reached prior to making ALC

adjustments. Attenuation

allows you to attenuate on a

per-sample basis until the

signal level is reduced below

the Threshold.

Smart Unlock

Many AKM S/PDIF Receivers

and Transceivers have two

features that make a

designer’s life and a

consumer’s experience

much better. Our Smart

Unlock Mode allows the chip

to continue running even if

lock is lost. When clock lock

is lost, AKM parts will revert

to the system crystal

(reference clock) . The built-

in dividers generate all

audio clocks, eliminating

external circuitry. AKM’s

Smart Filter mode handles

emphasis of S/PDIF signals.

If the AKM chip receives

emphasized audio formats, it

will correct this format prior

TDM: mucho

audio, 1-wire

As more and more audio

channels are required,

transferring these channels

to and from DSPs and

microcontrollers becomes a

major challenge. AKM has

chosen to support TDM

modes on many of its

multichannel DACs, ADCs

and codecs. TDM enables up

to 8 stereo streams to pass

over a single wire. This saves

DSP pins, simplifies routing

and makes an engineer’s job

much easier. AKM parts that

include TDM are the AK5384

ADC, several DACs (AK4355,

4356, 4357, 4358), and

codecs (4529, 4586, 4588,

4589, 4626, 4628).

The AK5384 supports standard TDM and daisy-chain TDM (shown

below), allowing up to 8-channels of audio over a single wire.

Converters

Sample rate converters are a

must in today’s digital audio

world. They simplify the

mixing of audio streams of

different sample rates and

provide a compatibility

bridge between audio

formats (44.1KHz to 48Khz,

44.1KHz to 96KHz, etc.).

Chips like the AK4120 and

AK4121 are perfect for

closed systems where digital

audio is coming from CD or

DVD, while the AK4122, with

its built-in S/PDIF receiver

facilitates easy interfacing to

Architecture

All AKM DSPs have a

pipeline core architecture

that gives this product

family its excellent audio

processing capabilities. The

pipeline (shown in red)

consists of a 24-bit x 16-bit

multiplier, 1- to 15-bit shift

control and a 34-bit ALU.

This pipeline allows

simultaneous multiply,

shifts, and ALU functions in

a single line of code. This

same line of code can also

control the coefficient, data

and delay pointers, can shift

data onto the bus, and store

the bus data in a memory

location or output port. This

single-line functionality

allows significant audio

processing using a relatively

low DSP master clock speed.

Input signal: -80dBFS Triangle waveform

...Lower Distortion, Better

Resolution

The images below clearly show the benefits of AKM’s Class D

amplifier technology. When a low-level signal is applied,

ordinary Class D approaches are forced to render the signal

using one of two voltage levels. AKM’s approach utilizes

intermediate voltage levels and Adaptive Dead-Time Control

for modulation. The result is increased resolution, lower

signal distortion.

Out-Of-Band Noise

Out of band noise generated by Class D amplifier’s can cause

problems during EMI testing (FCC, CE, etc.). AKM’s Class D

technology significantly reduces out of band noise. In doing

this, amplifiers based on the AK4730 can truly support 192KHz

sample rates and the extended frequency response that these

sample rates provide.

Class D amplifiers use pulse-width modulation (PWM) to generate the energy to drive external loudspeakers. Since PWM is a digital

technology, it is possible to have a pure digital signal path from source (CD, DVD) to speaker. The image on the left shows how an

analog sine wave is represented using PWM techniques. Most Class D technologies result in unacceptable THD+N (distortion) due to

the limitations of PWM. AKM has developed a technique that improves both the dynamic range the THD+N in digital amplifiers.

AKM’s Class D Technology offers Class AB performance with Class D efficiency. The input to an AKM Class D Amplifier is digital, not

analog. Unlike other solutions that use two voltage levels for modulation, AKM’s Class D products utilize multi-reference E-Bridge

technology to represent the signal that is transmitted to the speaker. This ability to use this intermediate voltage level to interpolate

the input signal results in improved dynamic range with less distortion. It sounds better and has fewer EMI issues than other offerings.

DACs+EEPROMs

In addition to making great audio DACs, AKM also makes DACs with integrated EEPROMs and stand-alone EEPROMs. These products

can be used as programmable voltage sources, taking the place of on-board trim pots and adding the ability to field update their values.

The DACs are very small and accurate. Thanks to the EEPROM, they retain their values even after power is removed from the circuit.
