1.2.2.4. Byte Deserializer

The byte deserializer allows the receiver channel to operate at higher data rates in a configuration that exceeds the FPGA fabric–transceiver interface frequency limit.

The byte deserializer supports operation in single- and double-width modes. The datapath clock rate at the input of the byte deserializer is twice the FPGA fabric–receiver interface clock frequency.

Note: You must use the byte deserializer in configurations that exceed the maximum frequency limit of the FPGA fabric–transceiver interface.

After byte deserialization, the word alignment pattern may be ordered in the MSByte or LSByte position.

Table 31.  Byte Deserializer Input Datapath Width ConversionData is assumed to be received as LSByte first—the least significant 8 or 10 bits in single-width mode or the least significant 16 or 20 bits in double-width mode.
Mode Byte Deserializer Input Datapath Width Receiver Output Datapath Width
Single Width 8 16
10 20
Double Width 16 32
20 40
