Precision Clock Generator (Direct Pin Routing)
The timing in
Table 18
and
Figure 15
is valid only when the
SRU is configured such that the precision clock generator
(PCG) takes its inputs directly from the DAI pins (via pin buff-
ers) 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 parameters and switching characteris-
tics apply to external DAI pins (DAI_P07 – DAI_P20).
