13  The Sparx5 SERDES interfaces share the same basic functionality, but
14  support different operating modes and line rates.
15
16  The following list lists the SERDES features:
17
18  * RX Adaptive Decision Feedback Equalizer (DFE)
19  * Programmable continuous time linear equalizer (CTLE)
20  * Rx variable gain control
21  * Rx built-in fault detector (loss-of-lock/loss-of-signal)
22  * Adjustable tx de-emphasis (FFE)
23  * Tx output amplitude control
24  * Supports rx eye monitor
25  * Multiple loopback modes
26  * Prbs generator and checker
27  * Polarity inversion control
28
