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