3.1.2.3. Input Sampler
The Input Sampler block is responsible for converting the serial input signal into a
retimed bit stream using the high-speed serial clock generated by the CDR block.
3.1.2.4. Deserializer
The deserializer block clocks in serial input data from the receiver buffer using the
high-speed serial recovered clock, and deserializes the data using the low-speed
parallel recovered clock. The deserializer forwards the deserialized data to the receiver
PCS or FPGA core.
The channel deserializer supports the following deserialization factors: 16, 20, 32, 40,
and 64.

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.
