3.1.2.5. Data Pattern Verifier

The data pattern verifier is used to verify the signal received at the receiver. The deserialized data pattern is sent to the data pattern verifier, which compares the received data pattern to the pattern it is configured to. There are several patterns which can be verified in NRZ and PAM4 mode. For the same setting, depending on the encoding mode, either PRBSx (NRZ) or PRBSxQ (PAM4) is configured.
