Part Number: CDCE6214

Hi,

As some PCIE device, it's clock is HCSL input, and the CDCE6214 is LPHCSL output, can we use LPHCSL to drive HCSL device?

For a PCIE4.0 application, can we use one LPHCSL to drive two HCSL device?

Thanks

Yes, LPHCSL output can be used to drive a HCSL input. The LP-HCSL spec was developed to be signal level compatible with HCSL so that the RX side doesn’t know the difference.

It is recommended to drive 1:1, one LPHCSL output to one HCSL receiver.

Kind regards,
Lane
