# Pin Description
5 ^{Control Interface Power (Input) - Positive power for the hardware/software control interface}
6 Regulator Voltage (Output) - Filter connection for internal voltage regulator
7, 19 ^{Ground (Input) - Ground reference}
8 ^{Recovered Master Clock (Output) - Outputs a master clock derived from LRCK}
9 Serial Audio Interface Power (Input) - Positive power for the serial audio interface
10 ^{Serial Clock (Input) - Serial bit-clock for the serial audio interface}
11 ^{Serial Audio Data Input (Input) - Input for two’s complement serial audio data}
Left/Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial
12 _{audio data line}
13 Test Output - These pins need to be floating and not connected to any trace or plane.
14, 15, Differential Analog Outputs (Output) - The full scale differential output level is specified in “DAC Ana-
22, 23 ^{log Characteristics - Commercial (-CZZ)” on page 9.}
16, 21 Mute Control (Output) - Control signals for optional mute circuit.
17 ^{Positive Voltage Reference (Output) - Positive reference voltage for the internal DAC}
18 Analog Power (Input) - Positive power supply for the analog section
20 ^{Quiescent Voltage (Output) - Filter connection for internal quiescent voltage}
