Analog Input Multiplexer
ADC3.
MCLK Frequency (Input) - Sets the required frequency range of the input Master Clock.
ADC3 High-Pass Filter Freeze (Input) - When this pin is driven high, the internal high-pass filter
will be disabled for ADC3.The current DC offset value will be frozen and continue to be subtracted
from the conversion result.
Reset (Input) - The device enters a low-power mode and all internal registers are reset to their
default settings when low.
Control Port Power (Input) - Determines the required signal level for the control port interface.
See
Frame Sync (Input) - Signals the start of a new TDM frame in the TDM digital interface format.
Digital Power (Input) - Positive power supply for the digital section.
Digital Ground (Input) - Ground reference for the digital section.
Serial Port Interface Power (Input) - Determines the required signal level for the serial port inter-
faces. See
Serial Clock (Input) - Serial clock for the serial audio interface. Input frequency must be 256 x Fs.
Master Clock (Input) - Clock source for the delta-sigma modulators and digital filters.
Serial Audio Data Output (Output) - TDM output for two’s complement serial audio data.
DAC Serial Audio Data Input (Input) - TDM Input for two’s complement serial audio data.
