# Pin Description
1 Reset (Input) - Powers down device when enabled.
2 Serial Audio Data (Input) - Input for two’s complement serial audio data.
3 Serial Clock (Input) -Serial clock for the serial audio interface.
4 Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the
serial audio data line.
5 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters.
