Martin Rowe mentioned that PRBS31 (pseudorandom bit sequence) has become the default compliance test pattern for emerging high rate standards. It was in
The following sequence can be used if using the training interface: a. Write to ipif address x03002A to set PRBS31 TX and RX bits (bits 4 and 5) (reg3.42) This will set the correct pins on the GT. b. Optionally, enable PMA Loopback with ipif reg x010000, bit 0. If you do...
1) Using the configuration vector and status vector instead of the MDIO interface 2) Using the Training Interface available for 10GBASE-KR The following sequence can be used if using the training interface: a. Write to ipif address x03002A to set PRBS31 TX and RX bits (bits 4 and 5) ...
