Martin Rowe mentioned that PRBS31 (pseudorandom bit sequence) has become the default compliance test pattern for emerging high rate standards. It was in
Solution The RX PRBS31 pattern checking is done in the GTX transceiver and the error count is read from the GT DRP registers via the DRP interface. If using RX PRBS31 pattern checking, this issue can be worked around by: 1) Using the configuration vector and status vector instead of the...
Hi Harson, The PRBS31 is a physical layer testing. Each lane (from the FPGA) will send out individual PRBS31 pattern, and each lane on the DAC will interpret it and check if the PRBS31 is received correctly. You do not need to separate it out on the JESD link ...
This creates dense regions for the approximate worst-case ISI pattern. In addition to DFE burst errors, QPRBS31 is identified as another major source of correlated errors in 56G+ PAM4 test systems, and can lead to more stringent FEC evaluation results. A two-stage FEC SG simulation method ...
1). DS250DF410 can automatically check incoming PRBS pattern and indicates if it is PRBS7. PRBS31, and etc. 2). Externally - through 100-ohm input of the 2nd channel- we should connect a differential cable or trace to the input of the PRBS checker channel. ...
