Pulse-Width Modulation Generators
Sample Rate Converter—Serial Input Port
The SRC input signals (SCLK, FS, and SDATA) are routed from
the DAI_P20–1 pins using the SRU. Therefore, the timing spec-
ifications provided in
Table 33
are valid at the DAI_P20–1 pins.
This feature is not available on the ADSP-21363 models.

DATA, SCLK, FS can come from any of the DAI pins. SCLK and FS can also come via PCG or SPORTs. PCG’s input can be either CLKIN or any of the DAI pins.
