Features:
Data path:
Features:
Input SPDIF to output DAC
Input ADC to outputs SPDIF or I
Crystal oscillator generates the clocks
for outputs SPDIF and I
PLL locks onto the SPDIF input signal
WS of I
Microcontroller mode:
– Decimator features can be used
– DAC sound features can be used
– SPDIF input channel status bits
– SPDIF output channel status bits
Input ADC to outputs SPDIF or I
Input I
Possibility to process input ADC, via
I
then to output DAC
Crystal oscillator generates the clocks
for outputs SPDIF and I
WSI is slave
WSO master
Microcontroller mode:
– Decimator features can be used
– DAC sound features can be used
– SPDIF output channel status bits
