Hi Team,

The LX2160A has 2 recovered or reconstructed clock. What is the use of these pins? Can I recover the PTP clock from the serdes via these pins. If possible how to do hardware connections.

These are the clocks recovered from SerDes lanes running Ethernet protocols (SGMII, XFI/USXGMII, 25G, etc) on SerDes 1 and 2.

No.

> If possible how to do hardware connections.

These are test pins which can be left unconnected.

Excuse me, these are test pins which can be left unconnected if not used for SerDes operation evaluation.
