The UDA1350AH is a low cost multi-purpose IEC 958 decoder DAC with a variety of operating modes.

In modes 1, 2, 3 and 4 the UDA1350AH is clock master; it generates the clock for both the outgoing and incoming digital

data streams. Consequently, any device providing data for the UDA1350AH via the data input interface in mode 4 will be

slave to the clock generated by the UDA1350AH.

In mode 5 the UDA1350AH locks to signal WSI from the digital data input interface. Conforming to IEC 958, the audio

sample frequency of the data input interface must be between 28.0 and 54.0 kHz.
