Input SPDIF to output I
Input I
Possibility to process input SPDIF, via
I
then to outputs DAC or SPDIF
BCK and WS being master for both I
input and output (different clocks)
Input I
BCK and WS being master; clocks
based on crystal oscillator
Microcontroller mode:
– DAC sound features can be used
– SPDIF output channel status bits
Input SPDIF to output DAC or I
Input I
Possibility to process input SPDIF, via

then to output SPDIF
Input SPDIF to outputs I
locking onto the SPDIF input signal;
BCK and WS being master
Input I
WS being master; clocks are
generated by the crystal oscillator
Microcontroller mode:
– DAC sound features can be used
– SPDIF input channel status bits
– SPDIF output channel status bits
