DFC0 and DFC1 inputs determine the major data flow options available in hardware mode, according to
Table 3.
S/AES is connected to VD+ in hardware mode 2, in order to select the serial audio input.
SFMT0 and SFMT1 select the serial audio input and output ports’ format. See Table 8.
Output section master clock input. The frequency must be 256x the output sample rate (Fso).
Audio data serial input pin.
Serial bit clock for audio data on the SDIN pin.
Word rate clock for the audio data on the SDIN pin. The frequency will be at the input sample rate (Fsi)
Input section recovered master clock output. Will be at a frequency of 256x the input sample rate (Fsi).
LOCK low indicates that the PLL is locked. This is also a start-up option pin, and requires a pull-up or
pull-down resistor.
