Clock Frequency (Input) - Determines the frequency of the clock expected to be driven into the
SYS_CLK pin. CLK_FREQ1 must be connected to DGND.
ADC/Serial Port (Input) - Selects between the Analog to Digital Converter and the Serial Port for
audio input. Selects the ADC when high or the serial port when low.
Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial
audio data line.
Serial Clock (Input) - Serial bit clock for the serial audio interface.
Serial Audio Data Input (Input) - Input for two’s complement serial audio data.
Mute (Input) - The PWM outputs will output silence as a 50% duty cycle signal when this pin is
driven low.
Reset (Input) - The device enters a low power mode and all internal registers are reset to their
default settings when this pin is driven low.
