D2-7xx83
Audio Processing Signal Flow Support
The D2-7xx83-series of ICs supports a wide variety of signal flows
and audio processing options that are fully programmable and
are completely defined by the system firmware and system
architecture.
The firmware provided for the D2-7xx83 devices is
application-specific and includes its own specific signal flow and
associated performance level. Much of the signal flow is also
hardware dependent and that hardware integrates with the full
system architecture that is defined within that system’s
programmed firmware. Each firmware design includes a specific
set of control tool support, including the D2Audio™ Audio
Canvas™ software and system design data.
Additional design-specific reference documentation is included
within each firmware application design, that includes
platform-specific signal flows, control registers, and descriptions
of advanced processing features.
The various system support capabilities include:
• Flexible system configuration with 8 audio input and audio
processing channels, with up to 12 audio output PWM
channels, supporting differential or single-end PWM outputs
with up to 18 PWM output pins.
• Audio processing for up to 4 simultaneous stereo
asynchronous digital audio inputs from a variety of sources
(HDA, I2S, HDMI, DSD, S/PDIF Digital)
• Multiple D2-7xx83 devices may be cascaded to support higher
channel count designs.
Functional Description
The D2-7xx83 Family of ICs, integrated into D2Audio’s offerings
of reference design platforms support present and future design
features with little or no additional hardware or logic to enable
new features.
Audio Input
Multiple versions of the D2-7xx83 family IC-based reference
designs support a wide range of market applications and each of
these market applications has a variety of potential audio
sources such as:
• Mono and Stereo Analog Inputs
• Serial Audio, I2S and Time Division Multiplexed (TDM) Single
Line “Network” Mode
• HD-Audio Interface (UAA-Class Driver Capable)
• Stereo and Multichannel DSD
• S/PDIF Digital (IEC60958-Compliant and IEC61937Compliant)
SERIAL AUDIO INPUT
Since most systems incorporate some mix of digital and analog
inputs, the DAE-6 offers a very flexible digital audio peripheral
interface. The DAE-6 features four independent Serial Audio
Interface (SAI) ports. All SAI ports support both master or slave
clocking and can support sample rates from 32kHz to 192kHz.
Each SAI port supports the digital audio industry I2S standard, which
supports carrying up to 24-bit Linear PCM audio words per subframe
IEC60958, or compressed digital audio (Dolby® Digital, AAC, DTS®,
MPEG, etc.) packing per the IEC61937 specification. The SAI port
also supports Left-Justified formatted Linear PCM or compressed
digital audio. Each SAI port supports time division multiplexing
(TDM) capability (a.k.a. “Network mode”) with up to 32 words per
frame.
SAI ports 2 and 3 (the 3rd and 4th ports) have multiplexed inputs
to provide a standard input signal flow for the ADC, DSD, and
HDA audio interfaces. All serial audio input data streams go
through an SAI interface, which simplifies the data flow
configuration.
SAI data formats are shown in Figure 5. For I2S format, the left
channel data is read when LRCK is low. For the Left-Justified
format, the left channel data is read when LRCK is high. Either
format requires data to be valid on the rising edge of SCLK and
sent MSB-first on SDIN with 32 bits of data per channel. Each set
of digital inputs runs asynchronously to the others and may
accept different sample rates and formats.

D2-7xx83
S/PDIF RECEIVER
ADC INPUT
The D2-7xx83 contains two input pins internally multiplexed into
one IEC60958 compliant S/PDIF Digital receiver. The receiver
input pins are 3.3V CMOS input level compatible, requiring
external circuitry to condition the serial input. The receiver
contains an input transition detector, digital PLL clock recovery,
and a decoder to separate audio, channel status, and user data.
Only the first 24-Channel status bits are supported. The receiver
constantly monitors the incoming data stream to detect the
IEC61937-1 packet headers, and if found, captures the Pc and
Pd data words into registers. The receiver meets the jitter
tolerance specified in IEC60958-4.
The D2-7xx83 contains a high-performance Analog-to-Digital
Converter (ADC) that connects to input analog sources with a
minimum of interface circuitry. At a bandwidth of 20kHz at
nominal voltage and temperature, the ADC input of the DAE-6
provides a typical THD+N (unweighted) value of -81dB and an
SNR/Dynamic Range of 94dB.
S/PDIF is a commonly used interface for receiving compressed
(IEC61937-compliant) and stereo PCM (IEC60958-compliant)
audio data. This interface also supports receipt of compressed
audio data that is not compliant with the IEC61937 specification,
but instead meets the IEC60958 specification.
0
The ADC master clock can be supplied from either the low jitter
PLL of the D2-7xx83, or from the HD Audio interface. When the
PLL provides the ADC master clock, the ADC operates
synchronous to the DSP processing, which minimizes noise
pickup. When operated from the HD Audio clock system, the ADC
decimator output is synchronous to the HDA frame rate,
eliminating the need for sample rate conversion to the HDA
frame rate. Figure 6 shows the ADC decimator frequency
response over full bandwidth and passband, and Figure 7 shows
the ADC performance with full scale input processed through the
SRC to a 48kHz sample rate.

D2-7xx83
DSD
The HDMI specification (version 1.2 and later) used in TV systems
supports streaming DSD encoded audio over HDMI. To support
this, the system can receive and process up to 6 DSD audio
streams. The DSD interface supports both standard and
phase-modulated data formats. A high-quality 16x decimator
engine converts all of the DSD data streams into 24-bit PCM
words with an FS of 176.4kHz using a 128-tap FIR filter. The DSD
decimation filter has a cutoff frequency of 50kHz and is
optimized for passband flatness.
SAI ports 2 and 3 support DSD format inputs. When the DSD
interface is enabled, all the pins of SAI 2 and the SC21 pin of
SAI3 become the DSD input signals. The 6 channels of DSD
audio are merged into 3 I2S PCM streams at a 176.4kHz sample
rate. These I2S streams are routed into both receivers on SAI 2
and the first receiver of SAI 3. The data is then passed to the
Sample Rate Converter (SRC). The SRC will rate-lock to the DSD
input clock and attenuate any jitter in the DSD input stream.
The DSD input processing clusters the DSD data into channel
pairs. This allows a flexible channel count of 2, 4, or all 6 DSD
data streams to be handled. Using 4-channel DSD frees the SAI 3
port for other uses. Similarly, using only 2-Channel DSD frees the
second SAI 2 port and the SAI 3 port for other uses.
The D2-7xx83 family of ICs also offers digital audio format
conversion support for DSD stereo format input to S/PDIF or I2S
format output, as well as DSD multichannel format input to
multiple I2S format output. This high-quality digital audio format
conversion path also offers the ability to reduce clock jitter in the
audio system introduced by certain transmission paths such as
HDMI.
This technique also enables consumer products to output a
downsampled and/or downmixed (if necessary) digital audio
output for audio that may not otherwise be made available to the
consumer in the original higher-bandwidth format due to certain
consumer electronic/content protection licensing restrictions.

Audio Output
PWM AUDIO AMPLIFIER OUTPUT
The D2-7xx83 family supports multiple PWM output topologies,
which enables system designs to use an output stage, which
meets the cost and performance requirements of the particular
application. Twelve PWM channels are mapped to 18 PWM
output pins by the programmed firmware. The PWM output pins
are 3.3V CMOS levels with either 8mA or 16mA drive capability.
Output topologies supported include:
• Half-bridge, N+N or N+P
• Full-bridge, N+N or N+P using 2-level modulation, 2 or
4-quadrant control
LINE LEVEL OUTPUT
In addition to amplified outputs, the D2-7xx83 family IC also
supports line-level outputs that generate a nominal 1VRMS
output using a simple passive filter.
PCM audio bitstream via a specified SAI port, or S/PDIF Digital
transmitter. In addition, depending on the firmware functionality,
it is possible for unused SAI (Serial Audio Interfaces) to also
support I2S output as well, in either slave or master mode. The
output audio sample rate is determined by the firmware and can
vary from 32kHz up to 192kHz.
HD Audio
HDA INTERFACE
The HD Audio interface also provides a control interface. This
control interface uses the HD Audio GPI, GPO, and GPIO 8-bit
ports to provide a message passing facility between the
D2-7xx83 and the PC.
The D2-7xx83 fully supports Windows® Hardware Quality Labs
(WHQL™)-certification as, it is a UAA-Compliant Secondary HD
Audio CODEC. The devices may be used either as the primary
HDA CODEC, or as the second HDA CODEC in the system.
Features supported are:
Headphone outputs or line-level outputs that require a 2VRMS (or
higher output level) are also supported, using an active filter to
accomplish the signal level needs.
• Message passing to other devices located on the motherboard
(e.g. HP jack detection and reporting.)
S/PDIF TRANSMITTER
• Amplifier code load during system boot.
The D2-7xx83 contains one IEC60958 compatible S/PDIF Digital
transmitter. The transmitter complies with the consumer
applications defined in IEC60958-3. The transmitter supports
24-bit audio data, 24-bit user data, and 30-bit channel status
data.
• Amplifier control protocol (D2Audio Canvas II support).
A bit-exact pass-through mode from the selected SPDIFRX[1:0]
input is also supported. This simplifies system designs that
require that the IEC61937-compliant original compressed audio
bitstream be made available at the back panel of the product, as
well as giving the user the capability to select a decoded (and
downmixed, if necessary) IEC60958-compliant stereo or mono
Linear PCM output for digital audio recording/playback
capabilities.
The D2-7xx83 family optional firmware offers digital audio
format conversion support for I2S Digital format input to S/PDIF
Digital format output, as well as S/PDIF Digital format input to
I2S Digital format output, for all digital audio Linear PCM
(non-compressed) audio sources. This functionality is not
available for compressed audio inputs, unless the compressed
audio data is first decoded by the internal DSP, and if necessary,
downmixed to 2 channels.
• Amplifier firmware download.
HD AUDIO PLAY
The D2-7xx83 provides for direct connection of a PC’s HD Audio
(HDA) Controller to the device. In this configuration, the
D2-7xx83 functions as an HDA CODEC with powered (amplified)
outputs.
Supported Features Include:
• 2, 4, 6, or 8 Amplified or PWM DAC Channels
• Audio Sample Rates 48kHz, 96kHz, 192kHz
• Data Widths of 16-bit, 20-bit, and 24-bit
• Independent Channel Gain Control
The HDA interface uses 5 of the 6 pins of the SAI 3 port. The HDA
interface captures the audio streams and converts them into one
to four I2S data streams, depending on the number of channels
used. These I2S stereo streams are routed through SAI 3 and SAI
4 and then on to the Sample Rate Converter. The SRC will rate
lock to the HDA stream and remove any jitter while converting
the data to the output sample rate.
This format conversion path offers the ability to reduce the clock
jitter on the output due to the fact that both inputs (when in this
mode) pass through the professional-grade Sample-Rate Converters
(SRC). This approach also enables consumer products to output a
downsampled digital audio output for audio that may not otherwise
be made available to the consumer in the original higher-bandwidth
format due to certain consumer electronic/content protection
licensing restrictions.
SERIAL AUDIO OUTPUT
D2-7xx83 family IC-based systems support outputting a bit-exact
pass-through of a compressed audio bitstream, or a decoded,
down-mixed (Lt/Rt or Lo/Ro) and downsampled 2 channel Linear

Sample Rate Converters (SRC)
D2-7xx83 family ICs support internal asynchronous sample rate
conversion to align input audio streams to a single rate
compatible with the DSP processing rate and PWM switch rate.
D2-7xx83 device family has 4 independent rate estimators,
allowing up to 4 asynchronous stereo inputs (8 channels) to be
sample rate converted and processed simultaneously. The
sample rate converter has a measured SNR that exceeds 140dB
and a THD+N that exceeds -125dB.
The PLL block contains the following components:
• Low noise crystal oscillator
• Low jitter PLL clock multiplier
• Power on reset generator
• Brown out detectors on the CVDD and RVDD supplies
• System reset generation logic
DSP
The majority of the D2-7xx83 audio processing functions as well
as system control occur within the DSP core. The core is a 24-bit
fixed-point Digital Signal Processor, tightly integrated with its
own DMA, interrupt control, memory, and control interfaces.
Software configurable processing blocks and signal routings are
implemented within the DSP, allowing a wide range of
functionality and system implementations through the
programmed definitions that are read into memory upon device
initialization. Signal flows through the device are buffered and
processed through hardware specific-function blocks (such as
the Sample Rate Converter) and allow considerable overall signal
processing capability through interface to the DSP.
Clocks And PLL
The clock generation contains a low jitter PLL critical for low
noise PWM output and a precise master clock source for the
Submit Document Feedback
ADC, sample rate conversion, and the audio data paths. The
serial audio interfaces can function as either a master or a slave.
24
• Clock generators for the DSP, S/PDIF transmitter, ADC, and
MCLK output pin
The PLL block is completely managed by the system firmware.
The system clock is provided by the crystal oscillator block, using
either a fundamental mode crystal or a clock input to the XTALI
pin. If the clock input is used, it must be a 1.8V signal level. The
input signal on the XTALI pin is analog buffered and driven onto
the OSCOUT pin for use in driving the XTALI input of other
D2-7xx83 controllers.
The PLL uses the signal on the XTALI pin as the reference clock.
The reference clock frequency is multiplied by an integer
multiple of 4 to 15 to get the PLL output clock. The PLL output is
used to time the PWM outputs and to generate the DSP clock.
During system start-up, before the PLL has been configured and
locked, the PLL is bypassed and the system operates at XTALI
speed.
FN7838.3
April 28, 2016
D2-7xx83
The power on reset circuit senses the rise of the PLLVDD supply.
When the supply reaches the sense threshold, the power on reset
pulse is generated. If the PLLVDD supply droops below the sense
threshold, the reset pulse will occur when the supply rises above
the threshold. The power on reset signal will drive the nRSTOUT
output pin low.
The two power supply brown out detectors monitor the CVDD and
PWMVDD power rails. If the power rail droops below the
threshold, the brown out detector will activate and drive the
nRSTOUT output pin low.
The system reset generation logic is activated by a low level on
the nRESET input pin or by the power on reset sensor pulse. Upon
de-assertion of nRESET a sequential counter ensures sufficient
time and clock cycle count for the internal synchronous logic to
reset.
Multiple D2-7xx83 ICs are capable of running on a common
timebase. Multiple D2-7xx83 ICs synchronize themselves onto a
single crystal oscillator so that all ICs run at identical
frequencies.
DSP CLOCK SPEED AND MEMORY CAPACITY SUPPORT
The D2-7xx83 devices are offered in part number-specific
devices that support multiple DSP clock speeds and memory
capacity. Depending on the device part number, the D2-7xx83
operates up to clock rates of 147.456MHz or 159.744MHz, and
offers memory capacity of 24k/24k/32k or 40k/40k, 56k of
X/Y/P memory space.
The higher speed and larger memory devices support designs
requiring higher processing capacity, while the lower speed
devices provide cost optimization to systems not requiring the
additional audio processing and decode capability.
Refer to “DAE-6 Device Feature Set Offering” on page 3 for the
device part numbers and definitions of clock speed and memory
capacity.
Hardware I/O Functions
The D2-7xx83 provides programmable I/O pins used for various
hardware functions of the system design. Pin functions are
defined by the product firmware, and may be different from one
design to another.
GENERAL-PURPOSE (GPIO) I/O PINS,
POWER SUPPLY SYNCHRONIZATION
The PSSYNC pin provides a power supply synchronization signal
for switching power supplies. Firmware configures PSSYNC to the
frequency and duty cycle needed by the system switching
regulator. The proper configuration eliminates audio output tones
generated if the switching power supply is not locked to the
amplifier switching.
POWER SUPPLY ANTI-PUMP
D2-7xx83 supports designs to correct for power supply pumping
that occurs in half-bridge output stage topologies. The PUMPHI
and PUMPLO pins provide a differential PWM signal pair that
drive an anti-pump correction stage. The dead time and duty
cycle are adjustable to eliminate the power supply DC offset.
Amplifier Protection
The D2-7xx83 supports individual PWM channel protection
through individual protection input pins. These PROTECT pins are
primarily intended for protecting the PWM powered output
stages. The protection inputs are activated by either a pulse or
level driven into the pin. Firmware configures the input
processing logic to properly interpret the input signal as rising
edge triggered, falling edge triggered, high level, or low level.
The protection input signal is generated by specialized sensing
circuits. There are several kinds of sensing circuits for detecting
current, temperature, or voltage. A powered PWM output stage or
a power supply pump driver typically uses an overcurrent sensor.
This sensor will detect power FET current, load current, or both.
These circuits are unique to the specific power stage design, and
may be embedded inside an integrated power stage.
Temperature and voltage sensing are accomplished in a variety
of ways and usually create a DC level representing a fault
condition.
D2-7xx83 designs incorporate a variety of protection strategies to
prevent damage from the high voltages, currents, and
temperatures present in class-D amplifier designs. This
protection is also effective against user-induced faults, such as
clipping, output overload, or output shorts, including both shorted
outputs or short-to-ground faults.
The D2-92xx IC works in conjunction with specific surrounding
parts to provide continuous system monitoring for destructive
events. These events include:
Eight dedicated General Purpose I/O (GPIO) pins are available for
system use. These are controlled only by the D2-7xx83 device
family firmware.
• Output Overcurrent
TIMERS
• Power Supply Brown Out
A timer block consisting of 3 separate general purpose timers
provides programmed control of event or count down timing
functions. The timer functions are controlled through the
firmware, where these timers can operate as timed pulse
generators, as pulse-width modulators, or as event counters to
capture an event or to measure the width or period of a
connected signal. These timers are connected to the 3 timer pins
(TIO[0:2]), which are also assignable as I/O by firmware.
• Shoot Through Overcurrent
Submit Document Feedback
25
• Output Short Circuit
• Over-Temperature (Thermal Event)
Protection features and their details are firmware application
dependent.
Firmware functions running on the D2-7xx83 can be assigned to
observe the temperature at critical points in the hardware and
automatically respond to excessive temperature. Depending on
the specific implementation, this response can be as simple as
turning on an optional fan to reduce temperature, or managing
the audio signal to reduce power consumption.
FN7838.3
April 28, 2016
D2-7xx83
GRACEFUL OVERCURRENT AND SHORT CIRCUIT
Overcurrent sensing requires a current sensor in the power
device to be protected, usually a powered PWM output. The
typical sensor creates a pulse that is active when the current
exceeds a specified threshold.
The D2-7xx83 IC observes the overcurrent protection inputs and
provides graceful protection for the output stage. The hardware is
configured to provide immediate current reduction, cycle-by-cycle
output clipping, output signal control, and output stage
deactivation depending on the severity and duration of high
current events. The combination of hardware features and
firmware monitoring allows the system to differentiate between
an overcurrent situation or a more serious short circuit condition.
At the de-assertion of nRESET, the chip will capture the boot
mode selection and begin the boot process.
Booting and Boot Modes
CODE INITIALIZATION AND BOOT MODES
D2-7xx83 includes a fully-programmable DSP with internal boot
ROM. The boot ROM’s primary function is to download a
second-stage boot image from one of several possible peripheral
sources:
• I2C Interface EEPROM
THERMAL PROTECTION
The D2-7xx83 IC can connect to an optional low-cost thermal
sensing circuit and monitor temperatures in the system.
Firmware monitoring can record the system temperature and
provide system responses including enabling a fan and
managing the audio output signal.
Device Operation
RESET AND INITIALIZATION
The D2-7xx83 must be reset after power up to begin proper
operation, and in normal system hardware configurations, the
reset occurs automatically via the reset hardware circuitry. The
chip contains power rail sensors, brown out detectors, on the 3.3V
and 1.8V power supplies. These brown out sensors will assert and
hold an internal Power-on Reset, which will disable the device until
the power supplies are at a safe level for the DSP to start. These
same brownout sensors will detect a power supply voltage droop
while the system is active and provide a safe amplifier shutdown.
POWER SEQUENCING
The CVDD and RVDD (including PWMVDD) supplies should be
brought up together to avoid high current transients that could
fold back a power supply regulator. The ADCVDD and PLLVDD
may be brought up separately. Best practice would be for all
supplies to feed from regulators with a common power source.
Typically this can be achieved by using a single 5V power source
and regulating the 3.3V and 1.8V supplies from that 5V source.
RESET
D2-7xx83 has one reset input: the nRESET pin. The nRESET input
pin (active low, non-reset high) is effectively a power-on system
reset. All internal state logic, except internal test hardware, is
initialized by nRESET. While reset is active the system is held in

the reset condition. The reset condition is defined as all internal
reset signals being active, the crystal oscillator is running, and
the PLL disabled.
26
• I2C Interface Slave
• SPI ROM
• SPI Interface Slave
• HDA Bus
The specific boot mode is selected based on the state of the
IRQD, IRQC, IRQB, and IRQA pins at the time of reset
de-assertion. The boot ROM code has been designed to handle
both encrypted and non-encrypted boot images from any of the
above storage locations. Boot modes are shown in Table 6 on
page 27.
The system requires external firmware to boot the internal DSP.
Internal ROM within the DAE-6 initiates the boot process to read
the boot records and firmware, to load into the internal DAE-6
memory.
There are multiple boot modes provided on the DAE-6 devices, as
shown in Table 6. The mode is selected by a hardware pull-up or
pull-down connection to each of the four boot mode (IRQ[D:A])
pins. (Modes not listed are reserved.) Boot sources include:
• I2C EEPROM
• SPI EEPROM or SPI Flash
• I2C Slave (to external Microcontroller)
• SPI Slave (to external Microcontroller)
• Asynchronous UART (RS-232 for PC Communication Mode as
well as D2-7xx83 Device to Device Communication Mode)
• HD Audio Bus
• Combo Mode with I2C EEPROM or SPI

APPLICATION FIRMWARE LOAD
MULTI-CONTROLLER IC COMMUNICATION
The application firmware is loaded either by the boot code or by a
multi-step process. Direct boot code loading occurs when the
selected boot mode successfully finds a boot image on the
expected peripheral interface and the image is successfully
loaded in memory. A multi-step boot is one in which the boot
code loads a program that manages the system boot.
The D2-7xx83 IC is capable of communicating and synchronizing
data and control information across multiple D2-7xx83 ICs. This
communication is to facilitate matrix mixing of all input channels
in a system and to allow precise phase alignment of the output
audio. Systems designs are capable of achieving outputs phase
aligned to within 1/2 sample at 192kHz. One D2-7xx83 IC acts
as the timing master, so all other D2-7xx83 ICs must then
operate as timing slaves. The setting of the each of the D2-7xx83
ICs is system-configuration specific and is detailed in the specific
RDP documentation.
Control Interfaces
I2C 2-WIRE INTERFACE
The D2-7xx83 family IC has two separate I2C 2-Wire compatible
ports. One is typically used for the external microcontroller
interface, and the other for D2-7xx83 family IC communication to
EEPROMs, or other compatible peripheral chips. Both I2C
interfaces are multi-master capable.
Registers are accessed through the I2C control interface. Since
the I2C bus has multiple slaves, the desired I2C target device
must be addressed. The specific I2C channel control address is
defined within the firmware that is loaded into the DAE-6 at boot
and initialization time. Typical addresses used in various
reference designs use the address of 0xB2, but the actual
address should be confirmed based on the firmware design
being used in the application.
SERIAL PERIPHERAL INTERFACE (SPI™)
The Serial Peripheral Interface (SPI) is an alternate serial
interface to the I2C interfaces. As a master, this interface
supports port extenders, EEPROMs, Flash, and various control
interfaces for more complex chips. As a slave, this provides an
alternate method for customers to communicate with the
system.
Submit Document Feedback
27
AUDIO SYNCHRONIZATION
Multiple D2-7xx83 ICs can be connected together and synchronized
for controlling events to meet phase alignment requirements.
Control Protocols provide for an external device communication
with the D2-7xx83 firmware while the amplifier is running. The
D2-7xx83 firmware has a peripheral device driver that
establishes communication with the external controller device.
The D2-7xx83 is always a slave. Communication can occur
through the HDA, I2C, and SPI ports. However control is provided
through only the I2C, and HDA ports, and control through the SPI
port is not supported.
CONTROL REGISTER SUMMARY
The control register interface provides a mechanism for an
external controller to manipulate the amplifier signal flow, and
provides access to the internal registers.
Each system design has its own firmware-dependent register
Application Programming Interface (API) and its own unique
signal flow. The control register definitions, bit fields, and data
format for each register are specified in that firmware API.

address bytes. Next, the master must send a repeated Start,
following with the device address with the read/write bit set to
read, and then read the next three data bytes. The master must
Acknowledge (ACK) the first two read bytes and send a Not
Acknowledge (NACK) on the third byte received and a Stop
condition to complete the transaction. The device's control
interface acknowledges each byte by pulling SDA low on the bit
immediately following each write byte. The device read function,
as shown in Figure 11, executes the following 11 steps as the I2C
bus master:
Registers and memory spaces are defined within the DAE-6
firmware for specific internal operation and control. In typical
reference designs, the highest-order byte of the register address
(bits 23:16) determines the internal address space used for
control read or write access, and the remaining 16 bits (bits
15:0) describe the actual address within that space. Refer to the
descriptions of the actual reference design firmware being used
in the application for specific definitions.
All reads or writes to registers (shown in Figures 10 and 11)
begin with a Start Condition, followed by the Device Address byte,
three Register Address bytes, three Data bytes and a Stop
Condition.
1. I2C START command
2. Transmit device I2C address with W
3. Transmit mode byte
Register writes through the I2C interface are initiated by setting
the read/write bit that is within the device address byte. The
device write function as, shown in Figure 10, executes the
following 9 steps as the I2C bus master:
4. Transmit upper memory address byte
5. Transmit lower memory address byte
6. Repeat START command
1. I2C START command
7. Transmit device I2C address with R
2. Transmit device I2C address with W
8. Receive data upper byte
3. Transmit mode byte
9. Receive data middle byte
4. Transmit upper memory address byte
10. Receive data lower byte
5. Transmit lower memory address byte
11. I2C STOP command or NACK
6. Transmit data upper byte
7. Transmit data middle byte
8. Transmit data lower byte
9. I2C STOP command
All reads to registers require two steps. First, the master must
send a dummy write, which consists of sending a Start, followed

Audio Processing Functions
Input Source Selection
Each system design has its own firmware-dependent signal flow.
This signal flow may be generic, or specifically designed for a
particular amplifier application and consists of input elements
connected to various signal processing blocks, routing the audio
data to an output element. The input elements consist of chip
peripherals used for audio input (I2S input, S/PDIF Digital
receiver, and ADC). The output elements include the chip I2S
output, S/PDIF Digital transmitter, and PWM outputs.
A source selection register specifies the action of a signal
multiplexer, which will implement a simple switching function.
The selected input will be routed to the block output unaltered.
All non-selected inputs will be ignored. Selections typically
include I2S inputs, S/PDIF Digital inputs, HD Audio inputs, and
ADC inputs.
Typical audio processing blocks include gain stages, mixers, tone
controls, compressors, limiters, equalizers, routers, loudness
contour, crossover filters, delays, as well as audio enhancement
features provided within the specific application firmware.
The input and output elements are configured by the firmware
application and the scope of I/O selection is generally specific to
the hardware of the particular application.
The signal processing blocks contain one or more parameters
that define the signal transfer characteristic of the block and a
mechanism for choosing the source and destination data
locations. The signal flow is created by connecting together the
signal processing blocks in the proper order to achieve the
overall system audio processing function.
Firmware Functions
D2-7xx83 IC contains a DSP supporting powerful audio
processing algorithms. Some of the standard audio algorithms
that are typically supported in all firmware loads. Other
algorithms are specific system design and firmware load
dependent.
Master Volume
A master volume function alters the level on all channels
simultaneously by applying the same gain/attenuation function
to each. A single parameter controls all channels.
Channel Attenuation
A channel attenuation function alters the level of a single
channel. A single parameter is provided for each channel.
Equalization
An equalization processing block consists of a single input and
output, and is characterized by how many frequency bands are
supported. Typical equalizers have 3-bands or 5-bands, although
multiple combinations are directly supported. Each frequency
band has 3 parameters - the center frequency, the filter Q, and
the filter gain.
Tone Control
Tone control provide simple bass and treble processing to the
audio signal. Each tone processing block includes two first-order
(6dB/octave) shelving filters, one each for bass and treble. Filters
include programmable corner frequency and gain settings.
Additional features support multiple system capabilities such as:
Excursion Control
• Automatic power-on amplifier calibration
Excursion processing provides dynamic control of the subwoofer
response. Three audio processing control adjustments are
provided for frequency settings, and three adjustments are
provided for Q parameter settings.
• Parameter control and status reporting
• Integrated power supply control and clock synchronization
• Automatic power supply high-voltage rail anti-pump control
• Automatic negative rail generation and bring-up control (for
select half-bridge designs where a ± rail is not already
supplied)
• Automatic cycle-by-cycle temperature sensing and system
response
• Automatic cycle-by-cycle current sensing and system response
• Input audio signal sensing and pop-free power-on/off via
D2Audio’s patented “Green Mode” algorithm with adjustable
threshold
• Dynamic adjustment of efficiency vs. distortion vs. output
power level via D2Audio’s patented “DynaTiming” algorithm
• AM radio interference avoidance mode allows for dynamic
switching of PWM engines when system microcontroller is in
AM Radio model

Mixer
Mixer configuration blocks have multiple input channels and as
many output channels as required by the system implementation.
The mixer has an input gain parameter for each input to every
mixing node. (e.g. An 8-input mixer with 12 outputs incorporates a
total of 96 independent gain adjustment parameters.) The
minimum gain parameter value is infinite attenuation, or mute.
Mixers
An input mixer provides a two-input, two-output mixing and
routing path. All inputs can be mixed at adjustable gain into any
combination of outputs. Programmable settings are continuously
adjustable from unity (0 dB) gain, through full cut-off.
Compressor/Limiter
The compressor/limiter processor is used to gracefully limit the
dynamic range of the audio signal. This is useful to prevent the
amplifier from clipping or to limit the amplifier output power.
Each compressor/limiter has configurable Compression Ratio,
Threshold, Attack and Release Time, as well as Makeup Gain.

D2-7xx83
Upward Compressor
Upward Compressors provide audio compression and limiting
functions but also provide an increase of signal level to inputs
below the threshold setting. Upward Compressors have
configurable Expansion Ratio, Threshold, Attack and Release
Time, as well as Makeup Gain. Controls are supported for Global
settings, Gate adjustment, and for Low Level Expansion.
Upward compressors support two inputs. One input receives the
audio that is processed by the compressor and passed to its
output. A separate side chain input is used as the reference input
for the processing algorithms.
Delay
A delay block simply adds delay to the audio signal. A single
delay parameter is used.
Crossover
Low-pass and high-pass filter blocks add frequency filtering to
the audio paths, providing appropriate signal processing for
speaker crossover functionality, including bi-amplified solutions,
and subwoofer low-pass filtering.
High/Low-Pass Filters
High-Pass and Low-Pass filter blocks are provided for each of the
5 output channels downstream of the Router and Stereo Mixer.
These provide a flexible Crossover function for all the output
channels, including provision for defining the subwoofer
channel’s frequency response.
Filters are implemented as cascaded elements, with elements
allocated for high-pass as well as for low-pass functionality, with
complete flexibility of assignment. Pre-defined filter types
including Butterworth, Bessel, and Linkwitz-Riley
implementations are also provided.
Routers
Routers provide individual audio path selection to any one of
available input channels. The router performs path assignment
only. It does not have a provision for gain or signal level
adjustment.
Audio Processing Enhancements and
Decoding
Depending on the device part number and design-specific
firmware definitions, the DAE-6 device supports a variety of
processing, decoding, virtualization, and pre/post processing
feature sets, as well as options for DSP clock speed and memory
capacity. Features and processing support are shown in
“DAE-6 Device Feature Set Offering” on page 3.
SoundSuite™ Processing
The D2Audio SoundSuite™ audio processing provides a full set of
enhancements to audio that greatly add to the quality and
listening experience of sound in wide scopes of consumer

exclusive set of Mastering Tools and Tuning Capabilities, and
have been developed and refined by Mark Levinson over the
course of his many years of recording experience. The Tools and
Capabilities allow for an extended Studio Quality Tuning that is
only available in the MightyCat™ Series of DAE-6 Processors.
The MightyCat™ algorithms are included within the D2MC-72083
and D2MC-76083 devices. Refer also to the “DAE-6 Device
Feature Set Offering” on page 3.
Loudness Contour
Loudness contour provides adjustment to allow for dynamically
and automatically enhancing the frequency response of the
audio program material relative to the master volume Level
setting. The Loudness Contour models the frequency response
correction as defined by the Fletcher/Munson audio response
curve. It provides for amplitude or volume changes to those
signals to which the ear does not respond equally at very low
listening levels.
