Sample Alignment
The dCS 900 & 902 align samples such that Word Clock out aligns with AES3
samples out, the rising edge of word clock aligning with the start of the first
illegal code in the X,Z subframe preamble and the falling edge aligning with the
start of the Y subframe preamble. The scope shots below were taken in Master
mode.
