LS1028A reference clocks

[mkraj]

Dear NXP support team

In the NXP LS1028A reference design 100MHz LP-HCSL clock was used for SerDes 1&2 reference and PCIe reference.

Can these clocks be 100 MHz HCSL instead of LP-HCSL?

Hi @mkraj 

The clock selected should be as per the specification mentioned in section# 3.16.2 of the LS1028A datasheet. And I believe the HCSL clock is as per the specification required for the SerDes clock.

Thanks
