1. PIN DESCRIPTION - PCM DATA MODE
RST 1 Reset (Input) - Powers down device and resets all internal registers to their default settings.
VL 2 Logic Power (Input) - Positive power for the digital input/output.
SDATA 3 Serial Audio Data (Input) - Input for two's complement serial audio data.
SCLK 4 Serial Clock (Input/Output) - Serial clock for the serial audio interface.
LRCK 5 Left Right Clock (Input/Output) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
MCLK 6 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
FILT+ 11 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
CMOUT 12 Common Mode Voltage (Output) - Filter connection for internal quiescent voltage.
AMUTEC 20 Mute Control (Output) - The Mute Control pin goes high during power-up initialization, reset, muting,
BMUTEC 13 power-down or if the master clock to left/right clock frequency ratio is incorrect.
