Input Sampling Point Delay
Default Sampling Point is 3/4. Adjust according to Figure on page 20.
Input Stream Bit Rate
Unused streams must be connected to ground.
If the internal system clock is used as the clock source, all the above data rates are
available. Otherwise, the data rate cannot exceed the selected clock source’s rate.
