96 kHz IEC 958 audio DAC
Preliminary specification
UDA1351H
The IEC 958 input audio data including the accompanying
pre-emphasis information is available on the output data
interface.
A lock indication signal is available on pin LOCK indicating
that the IEC 958 decoder is locked.
By default the DAC output and the data output interface
are muted when the decoder is out-of-lock. However, this
setting can be overruled in the L3 control mode.
