6.3 TIMING DIAGRAMS
6.3.1 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 (Cload_ OCLK)
tsckt = 4 + pad_timing (Cload_SCKT) - pad_timing (Cload_ OCLK)
tlrckt = 3.5 + pad_timing (Cload_LRCCKT) - pad_timing (Cload_ OCLK)
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.
b) OCLK in input.
