Power Supply Synchronization Clock (Output) - The PWM synchronized clock to the
switch mode power supply.
Crystal Oscillator Input (Input) - Crystal Oscillator input or accepts an external clock
input signal that is used to drive the internal PWM core logic.
Crystal Oscillator Output (Output) - Crystal Oscillator output.
External System Clock (Output) - Clock output. This pin provides a divided down clock
derived from the XTI input.
Digital Audio Input Master Clock (Input) - Master audio clock.
Digital Audio Input Serial Clock (Input) - Serial clock for the Digital Audio Input Inter-
face. The clock frequency is a multiple of the Left/Right Clock running at Fs.
Digital Audio Input Left/Right Clock (Input) - Determines which channel, Left or Right,
is currently active on the serial audio data line. The rate is determined by the sampling fre-
quency Fs.
Digital Audio Input Serial Data (Input) - Input for two’s complement serial audio data.
Mute (Input) - The device will perform a hard mute on all channels. All internal registers
are not reset to their default settings.
Serial Control Port Clock (Input) - Serial clock for the serial control port. Requires an
external pull-up resistor to the logic interface voltage in I²C mode as shown in the Typical
Connection Diagram.
Serial Control Data (Input/Output) - SDA is a data I/O line in I²C mode and requires an
external pull-up resistor to the logic interface voltage, as shown in the Typical Connection
Diagram.; CDOUT is the output data line for the control port interface in SPI mode.
Address Bit 1 (I²C)/Serial Control Data (SPI) (Input) - AD1 is a chip address pin in I²C
mode.;CDIN is the input data line for the control port interface in SPI mode.
Address Bit 0 (I²C)/Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in
I²C mode; CS is the chip select signal in SPI mode.
Interrupt Request (Output) - CMOS or open-drain interrupt request output. This pin is
driven to the configured active state to indicate that the PWM Controller has status data
that should be read by the host.
Reset (Input) - The device enters a low power mode and all internal registers are reset to
their default settings when low.
General Purpose Input, Output (Input/Output) - This pin is configured as an input follow-
ing a RST condition. It can be configured as a general purpose input or output which can
be individually controlled by the Host Controller.
General Purpose Input, Output (Input/Output) - This pin is configured as an input follow-
ing a RST condition. It can be configured as a general purpose input or output which can
be individually controlled by the Host Controller.
