Introduction
The TAS5036B is an innovative, cost-effective, high-performance 24-bit six-channel digital pulse width
modulator (PWM) based on Equibit technology. Combined with a TI digital amplifier power stage, these
devices use noise-shaping and sophisticated error correction algorithms to achieve high power efficiency and
high-performance digital audio reproduction. The TAS5036B is designed to drive up to six digital power
devices to provide six channels of digital audio amplification. The digital power devices can be six conventional
monolithic power stages (such as the TAS5110) or six discrete differential power stages using gate drivers
and MOSFETs.
The TAS5036B has six independent volume controls and mute. The device operates in AD and BD modes.
This all-digital audio system contains only two analog components in the signal chain—an LC low-pass filter
at each speaker terminal and can provide up to 96-dB SNR at the speaker terminals. The TAS5036B has a
wide variety of serial input options including right justified (16, 20, or 24 bit), I2S (16, 20, or 24 bit) left justified,
or DSP (16 bit) data formats. The device is fully compatible with AES standard sampling rates of 44.1 kHz,
48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz including de-emphasis for 44.1-kHz and 48-kHz sample
rates. The TAS5036B plus the TAS51xx power stage device combination was designed for home theater
applications such as DVD minicomponent systems, home theater in a box (HTIB), DVD receiver, A/V receiver,
or TV sets.

Architecture Overview
The TAS5036B is composed of six functional elements:
•
•
•
•
•
•
2.1
Clock, PLL, and serial data interface (IIS)
Reset/power-down circuitry
Serial control interface (IIC)
Signal processing unit
Pulse width modulator (PWM)
Power supply
Clock and Serial Data Interface
The TAS5036B clock and serial data interface contain an input serial data slave and the clock master/ slave
interface. The serial data slave interface receives information from a digital source such as a DSP, S/PDIF
receiver, analog-to-digital converter (ADC), digital audio processor (DAP), or other serial bus master. The
serial data interface has three serial data inputs that can accept up to six channels of data at data sample rates
of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. The serial data interfaces support
left justified and right justified for 16-, 20-, and 24-bits. In addition, the serial data interface supports the DSP
protocol for 16 bits and the I2S protocol for 24 bits.
The TAS5036B can function as a receiver or a generator for the MCLK_IN (master clock), SCLK (shift clock),
and LRCLK (left/right clock) signals that control the flow of data on the three serial data interfaces. The
TAS5036B is a clock master when it generates these clocks and is a clock slave when it receives these clocks.
The TAS5036B is a synchronous design that relies upon the master clock to provide a reference clock for all
of the device operations and communication via the I2C. When operating as a slave, this reference clock is
MCLK_IN. When operating as a master, the reference clock is either a TTL clock input to XTAL_IN or a crystal
attached across XTAL_IN and XTAL_OUT.
The clock and serial data interface has two control parameters: data sample rate and clock master or slave.
2.1.1 Normal-Speed, Double-Speed, and Quad-Speed Selection
The data sample rate is selected through a terminal (DBSPD) or the serial control register 0 (X02). The data
sample rate control sets the frequencies of the SCLK and LRCLK in clock slave mode and the output
frequencies of SCLK and LRCLK in clock master mode. There are three data rates: normal speed, double
speed, and quad speed.
Normal-speed mode supports data rates of 32 kHz, 44.1 kHz, and 48 kHz. Normal speed is supported in the
master and slave modes. Double-speed mode is used to support sampling rates of 88.2 kHz and 96 kHz.
Double speed is supported in master and slave modes. Quad-speed mode is used to support sampling rates
of 176.4 kHz and 192 kHz.
The PWM is placed in normal speed by setting the DBSPD terminal low or by setting the normal mode bits
in the system control register 0 (x02) through the serial control interface. The PWM is placed in double speed
mode by setting the DBSPD terminal high or by setting the double speed bits in the system control register.
Quad-speed mode is auto detected supported in slave mode and invoked using the I2C serial control interface
in master mode. In slave mode, if the TAS5036B is not in double speed mode, quad-speed mode is
automatically detected when MCLK_IN is 128Fs. In master mode, the PWM is placed in quad-speed mode
by setting the quad-speed bit in the system control register through the serial control interface.
If the master clock is well behaved during the frequency transition (the high or low clock periods are not less
than 20 ns) then a simple speed selection is simply performed by setting the DBSPD terminal or the serial
control register.
When the sample rate is changed, the TAS5036B temporarily suspends processing, places the PWM outputs
in a hard mute (PWM P outputs low; PWM M outputs high and all VALID signals low), resets all internal
processes, and suspends all I2C operations. The TAS5036B then performs a partial re-initialization and
noiselessly restarts the PWM output. The TAS5036B preserves all control register settings throughout this
sequence. If desired, the sample rate change can be performed while mute is active to provide a completely
silent transition. The timing of this control sequence is shown in Section 4.

SLES073—February 2003
Architecture Overview
If the master clock input can encounter high clock or low clock period of less than 20 ns while the data rates
are changing, then RESET should be applied during this time There are two recommended control procedures
for this case, depending upon whether the DBSPD terminal or the serial control interface is used. These
control sequences are shown in Section 4.

2.1.2 Clock Master/Slave Mode (M_S)
Clock master and slave mode can be invoked using the M_S (master slave) terminal.
This terminal specifies the default mode that is set immediately following a device RESET. The serial data
interface setting permits the clock generation mode to be changed during normal operation.
The transition to master mode occurs:
•
Following a RESET when M_S terminal has a logic high applied
The transition to slave mode occurs:
•
Following a RESET when M_S terminal has a logic low applied
2.1.3 Clock Master Mode
When M_S = 1 following a RESET, the TAS5036B provides the master clock, SCLK, and LRCLK to the rest
of the system. In the master mode, the TAS5036B outputs the audio system clocks MCLK_OUT, SCLK, and
LRCLK.
The TAS5036B device generates these clocks plus its internal clocks from the internal phase-locked loop
(PLL). The reference clock for the PLL can be provided by either an external clock source (attached to
XTAL_IN) or a crystal (connected across terminals XTAL_IN and XTAL_OUT). The external source attached
to MCLK_IN is 256 times (128 in quad mode) the data sample rate (Fs). The SCLK frequency is 64 times the
data sample rate and the SCLK frequency of 48 times the data sample rate is not supported in the master
mode. The LRCLK frequency is the data sample rate.

2.1.3.1
Crystal Type and Circuit
In clock master mode the TAS5036B can derive the MCLKOUT, SCLK, and LRCLK from a crystal. In this case,
the TAS5036B uses a parallel-mode fundamental-mode crystal. This crystal is connected to the TAS5036B
as shown in Figure 2–1.

2.1.4 Clock Slave Mode
In the slave mode (M_S = 0), the master clock, LRCLK, and SCLK are inputs to the TAS5036B. The master
clock is supplied through the MCLK_IN terminal.
As in the master mode, the TAS5036B device develops its internal timing from the internal phase-locked loop
(PLL). The reference clock for the PLL is provided by the input to the MCLK_IN terminal. This input is at a
frequency of 256 times (128 in quad mode) the input data rate. The SCLK frequency is 48 or 64 times the data
sample rate. The LRCLK frequency is the data sample rate. The TAS5036B does not require any specific
phase relationship between SRCLK and MCLK_IN, but there must be synchronization. The TAS5036B
monitors the relationship between MCLK, SCLK, and LRCLK. The TAS5036B detects if any of the three clocks
are absent, if the LRCLK rate changes more than 10 MCLK cycles since the last device reset or clock error,
or if the MCLK frequency is changing substantially with respect to the PLL frequency.
When a clock error is detected, the TAS5036B performs a clock error management sequence.
The clock error management sequence temporarily suspends processing, places the PWM outputs in a hard
mute (PWM_P outputs are low; PWM_M outputs are high, and all VALID signals are low), resets all internal
processes, sets the volumes to mute, and suspends all I2C operations.
When the error condition is corrected, the TAS5036B exits the clock error sequence by performing a partial
re-initialization, noiselessly restarting the PWM output, and ramping the volume up to the level specified in
the volume control registers. This sequence is performed over a 60 ms. interval. The TAS5036B preserves
all control register settings that were set prior to the clock interruption.
If a clock error occurs while the ERR_RCVRY terminal is asserted (low), the TAS5036B performs the error
management sequence up to the unmute sequence. In this case, the volume remains at full attenuation with
the PWM output at a 50% duty cycle. The volume can be restored from this latched mute state by triggering
a mute/unmute sequence by asserting and releasing MUTE either by using the terminal, the system control
register X01 D4, or the individual channel mute register D5–D0.

Architecture Overview
Alternatively, the TAS5036B can be prevented from entering the latched mute state following a clock error
when the ERR_RCVRY terminal or the error recovery I2C command (register X03 bit D2) is active by writing
x7F to the individual error recovery register (x04) and a x84 to x1F (a feature enable register).

2.1.6 DCLK
DCLK is the internal high frequency clock that is produced by the PLL circuitry from MCLK. The TAS5036B
uses the DCLK to control all internal operations. DCLK is 8 times the speed of MCLK in normal speed mode,
4 times MCLK in double speed, and 2 times MCLK in quad speed. With respect to the I2C addressable
registers, DCLK clock cycles are used to specify interchannel delay and to detect when the MCLK frequency
is drifting. Table 2–4 DCLK shows the relationship between Sample Rate, MCLK, and DCLK.

2.1.7 Serial Data Interface
The TAS5036B operates as a slave only/receive only serial data interface in all modes. The TAS5036B has
three PCM serial data interfaces to accept six channels of digital data though the SDIN1, SDIN2, SDIN3 inputs.
The serial audio data is in MSB first; 2s complement format.
The serial data interfaces of the TAS5036B can be configured in right justified, I2S, left-justified, or DSP modes.
This interface supports 32-kHz, 44.1-kHz, 48-kHz, 88-kHz, 96-kHz, 176.4-kHz, and 192-kHz data sample
rates. The serial data interface format is specified using the data interface control register. The supported word
lengths are shown in Table 2–5.
During normal operating conditions if the serial data interface settings change state, an error recovery
sequence is initiated.

I2S Timing
I2S timing uses an LRCLK to define when the data being transmitted is for the left channel or the right channel.
The LRCLK is low for the left channel and high for the right channel. A bit clock running at 48 or 64 times Fs
is used to clock in the data. There is a delay of one bit clock from the time the LRCLK signal changes state
to the first bit of data on the data lines. The data is written MSB first and is valid on the rising edge of the bit
clock. The TAS5036B masks unused trailing data bit positions. Master mode only supports a 64 times Fs bit
clock.

Architecture Overview
2.2
Reset, Power Down, and Status
The reset, power down, and status circuitry provides the necessary controls to bring the TAS5036B to the initial
inactive condition, achieve low power standby, and report system status.
2.2.1 Reset—RESET
The TAS5036B is placed in the reset mode by setting the RESET terminal low.
RESET is an asynchronous control signal that restores the TAS5036B to its default conditions, sets the valid
1–6 outputs low, and places the PWM in the hard mute state. Volume is immediately set to full attenuation
(there is no ramp down).
As long as the RESET terminal is held low, the device is in the reset state. During reset, all I2C and serial data
bus operations are ignored. Table 2–6 shows the device output signals while RESET is active.
Upon the release of RESET, if POWER_DWN is high, the system performs a 4-ms to 5-ms device initialization
and then ramps the volume up to 0 db using a soft volume update sequence. If MCLK_IN is not active when
RESET is released high, then a 4-ms to 5-ms initialization sequence is produced once MCLK_IN becomes
active.
During device initialization all controls are reset to their initial states. Table 2–7 shows the control settings that
are changed during initialization.
RESET should be applied during power-up initialization or while changing the master slave clock states.

Because the RESET is an asynchronous control signal, small clicks and pops can be produced during the
application (the leading edge) of this control. However, when RESET is released, the transition from the hard
mute state back to normal operation is performed synchronously using a quiet sequence.
If a completely quiet reset sequence is desired, MUTE should be applied before applying RESET.

Architecture Overview
2.2.2 Power Down—PDN
The TAS5036B can be placed into the power-down mode by holding the PDN terminal low. When power-down
mode is entered, both the PLL and the oscillator are shut down. Volume is immediately set to full attenuation
(there is no ramp down). The valid 1–6 outputs are immediately asserted low and the PWM outputs are placed
in the hard mute state. PDN initiates device power down without clock inputs. As long as the PDN terminal
is held low—the device is in the power-down (hard mute) state.
During power down, all I2C and serial data bus operations are ignored. Table 2–8 shows the device output
signals while PDN is active.

To place the device in total power-down mode, both RESET and power-down modes must be enabled. Prior
to bringing PDN high, RESET must be brought low for a minimum of 50 ns.
Because PDN is an asynchronous control signal, small clicks and pops can be produced during the application
(the leading edge) of this control. However, when PDN is released, the transition from the hard mute state back
to normal operation is performed synchronously using a quiet sequence.
If a completely quiet reset sequence is desired, MUTE should be applied before applying PDN.
2.2.3 General Status Register
The general status register is a read only register. This register provides an indication when a volume update
is in progress or one of the channels is inactive. The device id can be read using this register.
Volume update is in progress—Whenever a volume change is in progress due to a volume update
command or mute, this status bit is high.
Device identification code—The device identification code 1 0 0 1 1 is displayed.
No internal errors (all valid signals are high)—When there are no internal errors in the TAS5036B and all
outputs are valid, this status bit is high.
One or more valid signals are inactive—If low, one or more channels of the TAS5036B are not outputting
data. The valid signals for those channels are inactive.
This can be produced by one of three causes:
•
•
•
•
•
One or more of the clock signals are in error
ERROR recover is active (low)
The automute has silenced one or more channels that are receiving 0 inputs
MUTE has been set
Volume control has been set to full attenuation
If this signal is high, the TAS5036B is outputting data on all channels.

Architecture Overview
2.2.4 Error Status Register
The error status register indicates historical information on control signal changes and clock errors. This
register latches these indications when they occur. The indications are cleared by writing a 00(Hex) to the
register.
This register is intended as a diagnostic tool to be used only when the system is not operating correctly. This
is because the error status bits are set when the data rate, serial data interface format, or master/slave mode
is changed. As a result, this register indicates an error condition even though the system is operating normally.
This register should only be used while diagnosing transient error conditions.
Any clock error or control signal terminal change which occurs since the last time the error status register was
cleared is displayed. In using this register, the first step is to initialize the device and verify that all of the clock
signals are active. Then this register should be cleared by writing a 00(Hex). At this point, the register indicates
any errors or control signal changes.
This register indicates an error condition by a high for the following conditions:
•
•
•
•
•
•
•
FS ERROR
A control terminal change has occurred (M_S, DBLSPD)
LRCLK error
MCLK_IN count error
DCLK phase error with respect to MCLK_IN
MCLK_IN phase error with respect to DCLK
PWM timing error
If all bits of the register are low, no errors have occurred and no control terminals changed.
There is no one-to-one correspondence of clock error indication to a system error condition. A particular
system error can be indicated by one or more error indications in this register. The system error conditions
and the reported errors are as follows:
There is no correct number of MCLKs per LRCLK:
•
•
•
FS error has occurred or
LRCLK error or
MCLK_IN count error
LRCLK is absent:
•
LRCLK error
MCLK is the wrong frequency, changing frequency, or absent:
•
•
•

processing is performed using a high-speed 24-bit signal processing architecture. The TAS5036B performs
the following signal processing features:
• Individual channel soft volume with a range of 24 dB to –114 dB plus mute
• Soft mute
• Automute
• 50-µs/15-µs de-emphasis filter supported in the sampling rates 32 kHz, 44.1 kHz, and 48 kHz
2.3.1 Volume Control
The gain of each output can be adjusted by a soft digital volume control for each channel. Volume adjustments
are performed using a soft gain update s-curve, which is approximated using a second order filter fit. The curve
fit is performed over a transition interval between 41 ms and 65 ms.
The volume of each channel can be adjusted from mute to 24 dB to –114 dB in 0.5 dB steps. Because of the
numerical representation that is used to control the volume, at very low volume levels the step size increases
for gains of that are less than –96 dB. The default volume setting following power up or reset is 0 dB for all
channels. The step size increases linearly up to approximately –90 dB, see Figure 2–10.

Figure 2–10. Attenuation Curve
The volume control format for each channel is expressed in 8 bits. The volume for each channel is set by writing
8 bits via the serial control interface. The MSB bit is written first as in the bit position 0 (LSB position).
The volume for each channel can be set using a single or multiple address write operation to the volume control
register via the serial control interface. Changing the volume of all six channels requires that 6 registers be
updated.
To coordinate the volume adjustment of multiple channels simultaneously, the TAS5036B performs a delayed
volume update upon receiving a volume change command. Following the completion of the register volume
write operations, the TAS5036B waits for 5 ms for another volume command to be given. If no volume
command is issued in that period of time, the TAS5036B starts adjusting the volume of the channels that
received volume settings.

Architecture Overview
While a volume update is being performed, the system status register indicates that the update is in progress.
During the update, all subsequent volume control setting requests that are sent to the TAS5036B are received
and stored as a single next value for a subsequent update. If more than one volume setting request is sent,
only the last is retained.

2.3.2 Mute
The application of mute ramps the volume from any setting to noiseless hard mute state. There are two
methods in which the TAS5036B can be placed into mute. The TAS5036B is placed in the noiseless mute when
the MUTE terminal is asserted low for a minimum of 3 MCLK_IN cycles. Alternatively, the mute mode can be
initiated by setting the mute bit in the system control register through the serial control interface. The
TAS5036B is held in mute state as long as the terminal is low or I2C mute setting is active. This command uses
quiet entry and exit sequences to and from the hard mute state.
If an error recovery (described in the PWM section) occurs after a mute request has been received, the device
returns from error recovery with the channel volume set as specified by the mute command.
2.3.3 Auto Mute
Automute is an automatic sequence that can be enabled or disabled via the serial control interface. The default
for this control is enabled. When enabled, the PWM automutes an individual channel when a channel receives
from 5 ms to 50 ms of consecutive zeros. This time interval can be selectable using the automute delay
register. The default interval is 5 ms at 48 kHz. This duration is independent of the sample rate. The automute
state is exited when two consecutive samples of nonzero data are received. The TAS5036B exit from
automute is performed quickly and preserves all music information.
This mode uses the valid low to provide a low-noise floor while maintaining a short start-up time. Noise free
entry and exit is achieved by using the PWM quiet start and stop sequences.
2.3.4 Individual Channel Mute
Individual channel mute is invoked through the serial interface. Individual channel mute permits each channel
of the TAS5036B to be individually muted and unmuted. The operation that is performed is identical to the mute
operation; however, it is performed on a per channel basis. A TAS5036B channel is held in the mute state as
long as the serial interface mute setting for that channel is set.
2.3.5 De-Emphasis Filter
For audio sources that have been pre-emphasized, a precision 50-µs/15-µs de-emphasis filter is provided to
support the sampling rates of 32 kHz, 44.1 kHz, and 48 kHz. See Figure 2–11 for a graph showing the
de-emphasis filtering characteristics. De-emphasis is set using two bits in the system control register.

Pulse Width Modulator (PWM)
The TAS5036B contains six channels of high performance digital Equibit PWM modulators that are designed
to drive switching output stages (back ends) in both single-ended (SE) and H-bridge (bridge tied load)
configuration. The TAS5036B device uses noise shaping and sophisticated error correction algorithms to
achieve high power efficiency and high-performance digital audio reproduction.
The PWM provides six pseudo-differential outputs to drive six monolithic power stages (such as TAS5110)
or six discrete differential power stages using gate drivers (such as the TAS5182) and MOSFETs in
single-ended or bridged configurations. The TAS5036B also provides a high performance differential output
that can be used to drive an external analog headphone amplifier.
2.4.1 Clipping Indicator
The clipping output is designed to indicate clipping. When any of the six PWM outputs exceeds the maximum
allowable amplitude, the clipping indicator is asserted. The clipping indicator is cleared every 10 ms.
2.4.2 Error Recovery
Error recovery is used to provide error management and to permit the PWM output to be reset while preserving
all intervolume, interchannel delay, dc offsets, and the other internal settings. Error recovery is initiated by
bringing the ERR_RCVRY terminal low for a minimum 5 MCLK_IN cycles or by setting the error recovery bit
in control register 1. Error recovery is a level sensitive signal.
The device also performs an error recovery automatically:
•
When the speed configuration is changed to normal, double, or quad speed
•
Following a change in the serial data bus interface configuration
When ERR_RCVRY is brought low, all valid signals go low, and the PWM-P and PWM-M outputs go low. If
there are any pending speed configurations, these changes are then performed. When ERR_RCVRY is
brought high, a delay of 4 ms to 5 ms is performed before the system starts the output re-initialization
sequence. After the initialization time, the TAS5036B begins normal operation. During error recovery, all
controls and device settings that were not updated are maintained in their current configurations.
To permit error recovery to be used to provide TAS5100 error management and recovery, the delay between
the start of (falling edge) error recovery and the falling edge of valid 1 though valid 6 is selectable. This delay
can be selected to be either 6 µs or 47 µs.
During error recovery all serial data bus operations are ignored. At the conclusion of the sequence, the error
recovery register bit is returned to normal operation state. Table 2–11 shows the device output signal states
while during error recovery.

The transitions are done using a quiet entrance and exit sequence to prevent pops and clicks.
2.4.3 Individual Channel Error Recovery
Individual channel error recovery is used to provide error management and to permit the PWM output to be
turned off. Error recovery is initiated by setting one or more of the six error recovery bits in the error recovery
register to low.
While the error recover bits are brought low, the valid signals go to the low state. When the error recovery bits
are brought high, a delay of 4 ms to 5 ms occurs before the channels are returned to normal operation.
The delay between the falling edge of the error recover bit and the falling edge of valid 1 though valid 6 is
selectable. This delay can be selected to be either 6 µs or 47 µs.
The TAS5036B controls the relative timing of the pseudo-differential drive control signals plus the valid signal
to minimize the production of system noise during error recovery operations. The transitions to valid low and
valid high are done using an almost quiet entrance and exit sequence to prevent pops and clicks.
2.4.4 PWM DC-Offset Correction
An 8-bit value can be programmed to each of the six PWM offset correction registers to correct for any offset
present in the output stages. The offset correction is divided into 256 intervals with a total offset correction of
±1.56% of full scale. The default value is zero correction represented by 00 (hex). These values can be
changed at any time through the serial control interface.
2.4.5 Interchannel Delay
An 8-bit value can be programmed to each of the six PWM interchannel delay registers to add a delay per
channel from 0 to 255 clock cycles. The delays correspond to cycles of the high-speed internal clock, DCLK
(or alternatively the external PLL clock frequency). Each subsequent channel has a default value that is N
DCLKs larger than the preceding channel. The default values are 0 for the first channel and 76 for each
successive channel.
These values can be updated upon power up through the serial control interface. This delay is generated in
the PWM block with the appropriate control signals generated in the CTL block.
These values can be changed at any time through the serial control interface.
2.4.6 ABD Delay
A 5-bit value is used to delay the A PWM signals with respect to B PWM signals. The value is the same for
all channels. It can be programmed from 0 to 31 DCLK clock cycles. The default values is 17 DCLK clock cycles
(01011). These values can be changed at any time through the serial control interface.
NOTE:
The performance of a TDAA system is optimized by setting the PWM timing based upon the
type of back-end device that is used and the layout. These values are set during initialization
using the I2C serial interface.

Architecture Overview
2.4.7 PWM/H-Bridge and Discrete H-Bridge Driver Interface
The TAS5036B provides six PWM outputs, which are designed to drive switching output stages (back-ends)
in both single-ended (SE) and H-bridge (bridge tied load) configuration. The back-ends may be monolithic
power stages (such as the TAS5110) or six discrete differential power stages using gate drivers (such as the
the TAS55182) and MOSFETs in single-ended or bridged configurations.
The TAS5110 device is optimized for bridge tied load (BTL) configurations. These devices require a pure
differential PWM signal with a third signal (VALID) to control the MUTE state. In the MUTE state, the TAS5110
OUTA and OUTB are both low.

I2C Serial Control Interface
MCLK must be active for the TAS5036B to support I2C bus transactions. The TAS5036B has a bidirectional
serial control interface that is compatible with the I2C (Inter IC) bus protocol and supports both 100 KBPS and
400 KBPS data transfer rates for single and multiple byte write and read operations. This is a slave only device
that does not support a multi-master bus environment or wait state insertion. The control interface is used to
program the registers of the device and to read device status.
The TAS5036B supports the standard-mode I2C bus operation (100 kHz maximum) and the fast I2C bus
operation (400 kHz maximum). The TAS5036B performs all I2C operations without I2C wait cycles.
The I2C bus employs two signals; SDA (data) and SCL (clock), to communicate between integrated circuits
in a system. Data is transferred on the bus serially one bit at a time. The address and data are transferred in
byte (8 bit) format with the most significant bit (MSB) transferred first. In addition, each byte transferred on the
bus is acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with
the master device driving a start condition on the bus and ends with the master device driving a stop condition
on the bus. The bus uses transitions on the data terminal (SDA) while the clock is high to indicate start and
stop conditions. A high-to-low transition on SDA indicates a start, and a low-to-high transition indicates a stop.
Normal data bit transitions must occur within the low time of the clock period. These conditions are shown in
Figure 2–13. The master generates the 7-bit slave address and the read/write (R/W) bit to open
communication with another device and then waits for an acknowledge condition. The TAS5036B holds SDA
low during acknowledge clock period to indicate an acknowledgement. When this occurs, the master transmits
the next byte of the sequence. Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte).
All compatible devices share the same signals via a bidirectional bus using a wired-AND connection. I2C An
external pullup resistor must be used for the SDA and SCL signals to set the high level for the bus.

Figure 2–13. Typical I2C Sequence
There are no limits on the number of bytes that can be transmitted between start and stop conditions. When
the last word transfers, the master generates a stop condition to release the bus. A generic data transfer
sequence is also shown in Figure 2–13.
The 7-bit address for the TAS5036B is 001101X, where X is a programmable address bit. Using the CS0
terminal on the device, the LSB address bit is programmable to permit two devices to be used in a system.
These two addresses are licensed I2C addresses and do not conflict with other licensed I2C audio devices.
To communicate with the TAS5036B, the I2C master uses 0011010 if CS0=0 and 0011011 if CS0=1. In addition
to the 7-bit device address, an 8-bit register address is used to direct communication to the proper register
location within the device interface.
Read and write operations to the TAS5036B can be done using single byte or multiple byte data transfers.
2.5.1 Single Byte Write
As shown in Figure 2–14, a single byte data write transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. The read/write bit determines the direction
of the data transfer. For a write data transfer, the read/write bit is 0. After receiving the correct I2C device
address and the read/write bit, the TAS5036B device responds with an acknowledge bit. Next, the master
transmits the address byte or bytes corresponding to the TAS5036B internal memory address being
accessed. After receiving the address byte, the TAS5036B again responds with an acknowledge bit. Next, the
master device transmits the data byte to be written to the memory address being accessed. After receiving
the data byte, the TAS5036B again responds with an acknowledge bit. Finally, the master device transmits
a stop condition to complete the single byte data write transfer.

2.5.3 Single Byte Read
As shown in Figure 2–16, a single byte data read transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. For the data read transfer, a write followed
by a read are actually done. Initially, a write is done to transfer the address byte or bytes of the internal memory
address to be read. As a result, the read/write bit is 0. After receiving the TAS5036B address and the read/write
bit, the TAS5036B responds with an acknowledge bit. Also, after sending the internal memory address byte
or bytes, the master device transmits another start condition followed by the TAS5036B address and the
read/write bit again. This time the read/write bit is a 1 indicating a read transfer. After receiving the TAS5036B
and the read/write bit, the TAS5036B again responds with an acknowledge bit. Next, the TAS5036B transmits
the data byte from the memory address being read. After receiving the data byte, the master device transmits
a not acknowledge followed by a stop condition to complete the single byte data read transfer.

System Procedures for Initialization, Changing Data Rates, and
Switching Between Master and Slave Modes
4.1
System Initialization
Reset is used during system initialization to hold the TAS5036B inactive while power (VDD), the master clock
(MCLK_IN), the device control, and the data signals become stable. The recommended initialization
sequence is to hold RESET low for 24 MCLK_IN cycles after VDD has reached 3 V and the other control
signals (MUTE, PDN, M_S, ERR_RCVRY, DBSPD, and CS0) are stable.
Figure 4–1 shows the recommended sequence and timing for the RESET terminal duing system VDD voltage
and MCLK.

Figure 4–1. RESET During System Initialization
Within the first 2 ms following the low-to-high transition of the RESET terminal, the serial data interface format
should be set in the serial data interface control register using the I2C serial control interface. If the data rate
setting is other than the setting specificed by the DBSPD terminal, then the data rate should be set using the
DBSPD terminal or I2C interface within 2 ms. following the low-to-high transition of the RESET terminal.
The time available to set the I2C registers following the low-to-high transition of the RESET terminal can be
extended using the ERR_RCVRY terminal. While ERR_RCVRY is low, the TAS5036B outputs are held
inactive. Once the I2C control registers are set, the ERR_RCVRY terminal can be released and the TAS5036B
starts operation. Figure 4–2 shows how the ERR_RCVRY terminal can be used to extend the interval as long
as necessary to set the I2C registers following the low-to-high transition of the RESET terminal.

adjusting the following:
•
•
•
•
•
•
Volume
Data sample rate
Emphasis/deemphasis settings
Individual channel mute
Automute delay register
DC-offset control registers
If desired, the TAS5036B can be set to perform an unmute sequence following the low-to-high transition of
the ERR_RCVRY terminal or the error recovery I2C command (register X03 bit D2). This capability is set by
writing x7F to the individual error recovery register (x04) and an x84 to x1F (a feature enable register).
4.2
Data Sample Rate
If the master clock is well-behaved during the frequency transition (no MCLK_IN high or low clock periods less
than 20 ns) then a simple speed selection is performed by setting the DBSPD terminal or the serial control
register. If it is known at least 60 ms in advance that the sample rate is going to change, mute can be used
to provide a completely silent transition. The timing of this control sequence is shown in Figure 4–3 and
Figure 4–4.

However, if the master clock input can encounter a high clock or low clock period of less than 20 ns, then
RESET should be applied during this time. There are two recommended control procedures for this case,
depending upon whether the DBSPD terminal or the serial control interface is used. These control sequences
are shown in Figure 4–5 and Figure 4–6.
Because this sequence employs the RESET terminal the internal register settings are set to the default values.

System Procedures for Initialization, Changing Data Rates, and Switching Between Master and Slave Modes
Figure 4–5 shows the procedure to change the data rate using the DBSPD terminal and then restore the
register settings. In this example, the ERR_RCVRY terminal is used to hold off system re-initialization after
RESET is released. This permits the system controller to have as much additional time as necessary to restore
the register settings.
Once the data rate is set, the ERR_RCVRY and MUTE terminal signals are set high and the system
re-initializes.
