ADSP-21367/ADSP-21368/ADSP-21369

Precision Clock Generator (Direct Pin Routing)

This timing is only valid when the SRU is configured such that 
the precision clock generator (PCG) takes its inputs directly 
from the DAI pins (via pin buffers) and sends its outputs 
directly to the DAI pins. For the other cases, where the PCG’s 

inputs and outputs are not directly routed to/from DAI pins (via 
pin buffers) there is no timing data available. All timing param-
eters and switching characteristics apply to external DAI pins 
(DAI_P01–20).
