Input Data Port (IDP)
The timing requirements for the IDP are given in
Figure
DAI_P20–1 pins using the SRU. Therefore, the timing specifica-
tions provided below are valid at the DAI_P20–1 pins.

DATA, SCLK, FS can come from any of the DAI pins. SCLK and FS can also come via the precision clock generators (PCG) or SPORTs. PCG input can be either
SISFS
SIHFS
SISD
SIHD
IDPCLKW
IDPCLK
CLKIN or any of the DAI pins.
22. IDP Signals (SCLK, FS, SDATA) are routed to the
FS Setup Before SCLK Rising Edge
FS Hold After SCLK Rising Edge
SDATA Setup Before SCLK Rising Edge
SDATA Hold After SCLK Rising Edge
