10G PCS Pattern Generators
The 10G PCS supports the PRBS, pseudo-random pattern, and square wave pattern generators. You
enable the pattern generator or verifiers in the 10G PCS, by writing a 1 to the
TX Test Enable
and
RX
Test Enable
bits. The following table lists the offsets and registers of the pattern generators and verifiers
in the 10G PCS.
Note: The 10G PRBS generator inverts its pattern before transmission. The 10G PRBS verifier inverts the
received pattern before verification. You may need to invert the patterns if you connect to third-
party PRBS pattern generators and checkers.
Note: Note: All undefined register bits are reserved.
