APA3163
Function Description
Clock And PLL
The APA3163 is a slave device and receives signals from MCLK, SCLK, and LRCLK. The digital audio processor
(DAP) provides all sample rates and MCLK rates which defined in the clock control register.
The APA3163 checks to verify that SCLK is a particular value of 32fS, 48fS, or 64fS. The DAP only provides a 1×fS LRCLK.
The timing relationship of these clocks to SDIN is shown in subsequent sections.
Serial Data Interface
Serial data is an input transmitted to SDIN. The PWM outputs are derived from SDIN. Besides, the APA3163 DAP
receives left-justified, right-justified, and I2S serial data formats with 16, 20, or 24 bit.
PWM Section
The APA3163 DAP device is a high power efficiency and high-performance digital audio reproduction. A noise shaper
is used to increase dynamic range and SNR in the audio band. The PWM section receives 24bit PCM data from the
DAP and outputs two BTL PWM audio output channels.
The PWM section has individual channel dc blocking filters that can be enabled and disabled. The low pass filter cutoff
frequency is less than 1Hz. Besides, the PWM section includes individual channel de-emphasis filters for 44.1 and 48
kHz and can be enabled and disabled.
The adjustable maximum modulation limit of PWM section is from 93.8% to 98.4%.
I2C Compatible Serial Control Interface
The APA3163 DAP receives commands from a system controller through an I2C serial control slave interface. The
serial control interface supports both normal-speed 100kHz and high-speed 400kHz operations without waiting
states. As an added feature, even though the MCLK is absent, the interface operates.
For status registers, the serial control interface provides both single-byte and multi-byte read and write operations;
and for the general control registers, they associated with the PWM.

I2S Timing
I2S timing uses LRCLK to define the data for the left channel and the right channel when the data being transmitted.
For the left channel, the LRCLK is low; for the right channel, the LRCLK is high. A bit clock running at 32, 48, or 64 × fS
is used to clock in the data. When the LRCLK signal changes state, there is a delay of one bit clock from the time which
the first bit of data on the data lines. The data is written MSB first and is valid on the rising edge of bit clock. The DAP
masks unused trailing data bit positions.

APA3163
Function Description (Cont.)
I2C Serial Control Interface
The APA3163 DAP has a bidirectional I2C interface that compatible with the I2C (Inter IC) bus protocol. Besides, it
provides both 100kHz and 400kHz data transfer rates to single and multiple bytes write and read operations.
This is a slave only device, and it doesn’t support a multi-master bus environment or wait state insertion. The function
of the control interface is to read device status and to program the registers of the device.
The DAP supports the standard-mode I2C bus operation (100kHz maximum) and the fast I2C bus operation (400kHz
maximum). Without I2C wait cycles, the DAP performs I2C operations.
General I2C Operation
The I2C bus uses 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. With the most significant bit (MSB) transferred first, the address and
data can be transferred in byte (8bit) format. 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 SDA when 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. These conditions are shown in Figure 10. The master generates the 7bit slave
address and the read/write (R/W) bit to open communication with another device and then waits for an acknowledge
condition. The APA3163 holds SDA low during the acknowledge clock to indicate an acknowledgment. When this
occurs, the master transmits the next byte of the sequence.
Each device is addressed by a unique 7bit slave address plus R/W bit (1 byte). All compatible devices share the same
signals via a bidirectional bus using a wired-AND connection. An external pull-up resistor must be used for the SDA
and SCL signals to set the high level for the bus.

Figure 10. Typical I2C Sequence
There is no limit 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 shown in
Figure 10.
The 7bit address for APA3163 is 0011 010 (0x34). APA3163 address can be changed from 0x34 to 0x38 by writing 0x38
to device address register 0xF9.

APA3163
Function Description (Cont.)
Single- and Multiple-Byte Transfers
The serial control interface supports single-byte and multiple-byte (R/W) operations for sub-addresses 0x00 to 0x1F.
However, for the sub-addresses 0x20 to 0xFF, the serial control interface supports only multiple-byte read/write
operations (in multiples of 4 bytes).
During multiple-byte read operations, the DAP responds with data, a byte at a time, starting at the sub-address
assigned, as long as the master device continues to respond with acknowledges. If a particular sub-address does
not contain 32 bits, the unused bits are read as logic 0.
During multiple-byte write operations, the DAP compares the number of bytes transmitted to the number of bytes that
are required for each specific sub-address.
Supplying a sub-address for each sub-address transaction is referred to as random I2C addressing. The APA3163
also supports sequential I2C addressing. For write transactions, if a sub-address is issued and followed by data for
that sub-address and the 15 sub-addresses that follow, a sequential I2C write transaction has taken place, and the
data for all 16 sub-addresses is successfully received by the APA3163. For I2C sequential write transactions, the subaddress then serves as the start address, and the amount of data subsequently transmitted, before a stop or start is
transmitted, determines how many sub-addresses are written. As was true for random addressing, sequential
addressing requires that a complete set of data be transmitted. If only a partial set of data is written to the last subaddress, the data for the last sub-address is discarded. However, if all other data written is accepted, only the
incomplete data is discarded.
Single-Byte Write
As shown in Figure 11, a single-byte data write transfer begins with the master device transmitting a start condition
followed by the I2C device address and the R/W bit. The R/W bit determines the direction of the data transfer. For a write
data transfer, the R/W bit will be a 0. After receiving the correct I2C device address and the R/W bit, the DAP responds
with an acknowledge bit. And then, the master transmits the address byte or bytes corresponding to the APA3163
internal memory address being accessed. After receiving the address byte, the APA3163 responds with an acknowledge bit again. Next, the master device transmits the data byte to be written to the memory address being accessed.
After receiving the data byte, the APA3163 again responds with an acknowledge bit. Finally, the master device transmits a stop condition to complete the single-byte data write transfer.

As shown in Figure 13, a single-byte data read transfer begins with the master device transmitting a start condition

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 R/W bit becomes a 0. After receiving the APA3163 address and the read/write bit, APA3163 responds
with an acknowledge bit. Besides, after sending the internal memory address byte or bytes, the master device
transmits another start condition followed by the APA3163 address and the read/write bit again. This time the read/
write bit becomes a 1, indicating a read transfer. After receiving the address and the read/write bit, the APA3163 again
responds with an acknowledge bit. And then, the APA3163 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.

The decimal value of a 3.23 format number can be found by following the weighting and is shown in Figure 18. If the
MSB is logic 0, the number is a positive number, and the weighting shown yields the correct number. If the MSB is a
logic 1, and then the number is a negative number. In this case, every bit must be inverted, a 1 added to the result, and
then the weighting shown in Figure 19 applied to obtain the magnitude of the negative number.

Recommended Command Sequences
The DAP has two groups of commands. One set is for configuration and is intended for use only during initialization.
The other set has built-in click and pop protection and may be used during normal operation while audio is streaming.
The following supported command sequences illustrate how to initialize, operate, and shutdown the device.
Initialization Sequence
Use the following sequence to power-up and initialize the device:
1. Hold all digital inputs low and ramp up AVDD/DVDD to at least 3V.
2. Initialize digital inputs and PVDD supply as follows:
• Drive RST=0, SD=1, and other digital inputs to their desired state while ensuring that all are never more than 2.5V
above AVDD/DVDD. Provide stable and valid I2S clocks (MCLK, LRCLK, and SCLK). Wait at least 100µs, drive
RST=1, and wait at least another 13.5ms.
• Ramp up PVDD to at least 8V while ensuring that it remains below 6V for at least 100µs after AVDD/DVDD reaches
3V. Then wait at least another 10µs.
3. Configure the DAP via I2C (see Users’s Guide for typical values): biquads (0x29-36)DRC parameters (0x3A-3C,
0x40-42, and 0x46) Bank select (0x50).
4. Configure remaining registers.
5. Exit shutdown (sequence defined below).
Normal Operation
The following are the only events supported during normal operation:
(a) Writes to master/channel volume registers
(b) Writes to soft mute register
(c) Enter and exit shutdown (sequence defined below)
(d) Clock errors and rate changes
Note: Events (c) and (d) are not supported for 240ms+1.3xt0 0after trim following AVDD/DVDD power up ramp (where Tstart is
specified by register 0x1A).

Shutdown Sequence
Enter:
1. Ensure I2S clocks have been stable and valid for at least 50ms.
2. Write 0x40 to register 0x05.
3. Wait at least 1ms+1.3xtstop (where tstop is specified by register 0x1A).
4. Once in shutdown, stable clocks are not required while device remains idle.
5. If desired, reconfigure by ensuring that clocks have been stable and valid for at least 50ms before returning to step
4 of initialization sequence.
Exit:
1. Ensure I2S clocks have been stable and valid for at least 50ms.
2. Write 0x00 to register 0x05 (exit shutdown command may not be serviced for as much as 240ms after trim following
AVDD/DVDD powerup ramp).
3. Wait at least 1ms+1.3xtstart (where tstart is specified by register 0x1A).
4. Proceed with normal operation.
Power-down Sequence
Use the following sequence to power-down the device and its supplies:
1. If time permits, enter shutdown (sequence defined above); else, in case of sudden power loss, assert SD=0 and
wait at least 2ms.
2. Assert RST=0.
3. Drive digital inputs low and ramp down PVDD supply as follows:
• Drive all digital inputs low after RST has been low for at least 2µs.
• Ramp down PVDD while ensuring that it remains above 8V until RST has been low for at least 2µs.
4. Ramp down AVDD/DVDD while ensuring that it remains above 3V until PVDD is below 6V and that it is never more
than 2.5V below the digital inputs.

Error Status Register (0x02)
The error bits are sticky and are not cleared by the hardware. This means that the software must clear the register
(write zeroes) and then read them to determine if they are persistent errors. Error Definitions:
MCLK Error : MCLK frequency is changing. The number of MCLKs per LRCLK is changing.
SCLK Error: The number of SCLKs per LRCLK is changing.
LRCLK Error: LRCLK frequency is changing.

System Control Register 1 (0x03)
The system control register 1 has several functions:
Bit D7: If 0, the dc-blocking filter for each channel is disabled. If 1, the dc-blocking filter ( -3dB cutoff < 1Hz ) for each
channel is enabled (default).
Bit D5: If 0, use soft unmute on recovery from clock error. This is a slow recovery. Unmute takes same time as volume
ramp defined in reg 0x0E. If 1, use hard unmute on recovery from clock error (default). This is a fast recovery, a single
step volume ramp Bits D1-D0: Select de-emphasis.

Function Description (Cont.)
Error Reporting
Any fault resulting in device shutdown is signaled by the ERROR pin going low (see Table 18). A sticky version of this
pin is available on D1 of register 0X02.
Table 16. ERROR Output States
Fault Description
Error
0
Over-Current (OC) or Under-Voltage (UVP) or Over-Temperature (OTP)
1
No faults (normal operation)
Over-Current (OC) Protection With Current-Limiting
The device has independent, fast-reacting current detectors on all high-side and low-side power-stage FETs. The
detector outputs are closely monitored by two protection systems. The first protection system controls the power
stage in order to prevent the output current further increasing, i.e., it performs a cycle-by-cycle current-limiting function,
rather than prematurely shutting down during combinations of high-level music transients and extreme speaker load
impedance drops. If the high-current condition situation persists, i.e., the power stage is being overloaded, a second
protection system triggers a latching shutdown, resulting in the power stage being set in the high-impedance (Hi-Z)
state. The device returns to normal operation once the fault condition (i.e., a short circuit on the output) is removed.
Current limiting and overcurrent protection are not independent for half-bridges.
That is, if the bridge-tied load between half-bridges A and B causes an overcurrent fault, half-bridges A, B, C, and D are
shut down.
Over-Temperature Protection
The APA3163 has over-temperatureprotection system. If the device junction temperature exceeds 150°C (nominal),
the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the high-impedance (Hi-Z)
state and FAULT being asserted low. The APA3163 recovers automatically once the temperature drops approximately
30°.
Under-Voltage Protection (UVP) and Power-On-Reset (POR)
The UVP and POR circuits of the APA3163 fully protect the device in any power-up/down and brownout situation.
While powering up, the POR circuit resets the overload circuit (OLP) and ensures that all circuits are fully operational
when the PVDD and AVDD supply voltages reach 7.6V and 2.7V, respectively. Although PVDD and AVDD are independently monitored, a supply voltage drop below the UVP threshold on AVDD or either PVDD pin results in all half-bridge
outputs immediately being set in the high-impedance (Hi-Z) state and ERROR being asserted low.
