5.4. TIMING DIAGRAMS
5.4.1. Audio DAC Interface
a) OCLK in output. The audio PLL is used to clock the DAC
tsdo = 3.5 + pad_timing (Cload_SDO) - pad_timing
tsckt = 4 + pad_timing (Cload_SCKT) - pad_timing
tlrckt = 3.5 + pad_timing (Cload_LRCCKT) -
b) OCLK in input.

Tlo min = 3ns
Toclk min = 25ns
tsdo = 5.5 + pad_timing (Cload_SDO) ns

Pad-timing versus load
Cload_XXX is the load in pF on the XXX output.
pad_timing (Cload_XXX) is the propagation delay
added to the XXX pad due to the load.
