16 Auxiliary Serial Clock (Output) - Serial clock for the Auxiliary serial audio interface.
17 Auxiliary Serial Input (Input) - The CS42432 provides an additional serial input for two’s comple-
ment serial audio data.
20,19 Differential Analog Output (Output) - The full-scale differential analog output level is specified in
21,22 the Analog Characteristics specification table. Each positive leg of the differential outputs may also
24,23 be used single-ended.

47 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-
cuits.
1.1 Digital I/O Pin Characteristics
Various pins on the CS42432 are powered from separate power supply rails. The logic level for each input
should adhere to the corresponding power rail and should not exceed the maximum ratings.
