Sample Rate Converter—Serial Output Port
For the serial output port, the frame-sync is an input and should
meet setup and hold times with regard to the serial clock on the
output port. The serial data output has a hold time and delay
Table 32. SRC, Serial Output Port
specification with regard to serial clock. Note that the serial
clock rising edge is the sampling edge and the falling edge is the
drive edge.

The data, serial clock, and frame sync signals can come from any of the DAI pins. The serial clock and frame sync can also come via PCG or SPORTs. PCG’s input can be
either CLKIN or any of the DAI pins.
