Digital Audio receiver ICs like DIR9001 and CS8414 mention the diff
voltage level at their input pins RXP and RXN as 200mv min while the
Digital Audio Transsmitters like DIT4096 and CS8406 use 5V logic
levels. How are they compatible with wide difference in levels? I am
looking at using them for SPDIF transmission and reception.

For standard SPDIF you'd normally use a voltage divider and an
isolation transformer on the output side. Look at 15.2, Isolating
Transformer Requirements, in the CS8406 datasheet.
