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.
