8.1
The UDA1351H is a low cost multi-purpose IEC 958 decoder DAC with a variety of operating modes.
In modes 1, 2, 3 and 4 the UDA1351H is clock master; it generates the clock for both the outgoing and incoming digital
data streams. Consequently, any device providing data for the UDA1351H via the data input interface in mode 4 will be
slave to the clock generated by the UDA1351H.
In mode 5 the UDA1351H 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 100.0 kHz.
