QPRBS13 QPRBS31 PRBS13Q PRBS31Q SSPR SSPR1 SSPRQ |
User-defined pattern (up to 320 bits) |
The data pattern verifier contains a receiver built-in self test (BIST) bit error checker. The receiver can check standard data patterns for link verification applications by enabling the PRBS mode in both the receiver link and a compatible transmitter link connected by a common transmission path or loopback.
Note:
- PRBS13Q, PRBS31Q are defined in IEEE Std 802.3bs-2017.
- QPRBS13 is defined in IEEE Std 802.3 94.2.9.3.
- SSPR is Short Stress Pattern Random test pattern. It is defined in OIF CEI 3.1 2.D.2
- SSPR1 is defined in OIF CEI 3.1 2.D.2.
- SSPRQ is defined in IEEE 802.3 120.5.11.2.3.
