LX2160A Reconstructed Clock

[muhammed_mufeed]

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.

Hi Ufedor,

Then what is the use of these recovered clock. Can I connect this recovered clock to a network synchronizer.

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

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