Preliminary Technical Data

Asynchronous Sample Rate Converter (ASRC)—Serial Input Port

The ASRC input signals are routed from the DAI0_PINx pins using the SRU. Therefore, the timing specifications provided in Table 48 are

valid at the DAI0_PINx pins.

Table 48. ASRC, Serial Input Port

All specifications are based on simulation data and are subject to change without notice.

1 The serial clock, data, and frame sync signals can originate from any of the DAI pins. The serial clock and frame sync signals can also originate via PCG or SPORTs. The

input of the PCG can be either CLKIN or any of the DAI pins.
