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! 2 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 The high-frequency clocks used in digital systems (CPU/system to a voltage output. clocks, memory clocks, etc.) can cause problems in the analog AKM DACs are voltage audio domain. Separate ground and power planes, short power output devices, simplifying traces and judicious routing of clock signals all play a part in getting the best performance from your design. If you have any external circuitry. AKM's superior outquestions, AKM Application Engineers are happy to review of-band noise your design and help you find problem areas. Here are a few performance pointers to help you get started with AKM audio: eliminates complex multi-pole filters, Isolate the analog and digital ground planes. relying instead on Place small bypass capacitors as close to the chip as simple one or twopossible pole designs. Do not place inductors in the power supply lines, as these restrict the flow of current to the chip and can reduce performance. Good PCB layout is crucial to great audio. 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 frequencies is crucial in providing spatial cues. AKM DACs and A/D converters 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 4 and Analog Worlds 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. 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! 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.) 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. 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 Pro. 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. 7 Watch Your Power Supply. 10 Noise is a performance killer. Make sure that your power supply is clean and strong. This will improve audio performance throughout 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. 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.

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 20Hz20KHz. 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!

There are advantages and disadvantages to both approaches, which forces some designers to make a difficult choice. With AKM, however, the choice is easy. Our AK4357, AK4358 and AK4383 support both formats in a single chip. The savvy engineer can use these devices to create true "universal" disc players. Technology Spotlight EDF AKM's DACs feature the industry's best integrated digital filter. This Extraordinary Digital Filter, or EDFTM, is the result of years of experience in both electrical and process engineering. This filter, combined with AKM's superior noiseshaping 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 Extraordinary Digital Filter DAC (yellow plot). The out of band noise and overall noise floor is significantly reduced by the EDF. The Extraordinary Digital Filter is found on many AKM highperformance DACs.

Many devices can be ordered in "High-reliability" configurations that meet or exceed ISO9001 specifications. The following AKM parts are certified for automotive use: S/PDIF, SRC - AK4112B, AK4121 DACs - AK4358, AK4381, AK4384 Codecs - AK4550, AK4586, AK4628 ADC - AK5355, AK5381, AK5383, AK5384 Technology Spotlight 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 instantaneously "step" the clipped value down by the Attenuation 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.

The built-in clock dividers automatically generate all audio clocks, eliminating costly external circuitry. Smart filter mode - if the incoming S/PDIF stream stops unexpectedly, the AK4114/5 will generate clocks using an external oscillator automatically. This makes the AK4114/5 the perfect master clock for audio systems.

Applications Spotlight 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 builtin 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 to retransmission. Technology Spotlight 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 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. Page 19 Bwr wi d ging the Digital w. a k m . c o m Class-D Digital Power Amplifier Technology 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.

AKM's Class D technology significantly reduces out of band noise. In doing this, amplifiers based on the AK4730 can truly support 192KHz Normal Class D out-of-band noise sample rates and the extended frequency response that these sample rates provide. AKM out-of-band noise ...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. Page 20 Input signal: -80dBFS Triangle waveform and Analog Worlds 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.
