3.10 Byte and word alignment

The word alignment function is performed under control of the EN_CDET signal.

When EN_CDET is high, the word alignment function is operational. If an improperly aligned

comma is encountered, the internal data is shifted to realign the comma character at the

deserializer output (RX[0:9]). In this process, up to three characters prior to the comma

character may be corrupted.

3.11 Clock recovery

The clock recovery block generates the two receiver byte clocks RBC[0:1] at half the

frequency corresponding to the RX+/RX- byte data rate. These two byte clocks are 180

° out

of phase with each other. They are alternatively used to clock the 10-bit parallel output data.
