CDCM7005: LVPECL input clock to CDCM7005

Part Number: CDCM7005

Hi Team,

My customer is planning to give LVPECL input clock to CDCM7005, customer is using CMOS to LVPECL converter. They are setting common mode voltage as 2V nominal and 0.8V to 1V as Vpk-pk (referring SLLA120).

Can you please confirm.

Regards, Shinu Mathew.

Hello Shinu,

This device is expecting Common-mode input voltage (Vic) of LVPECL input to be between 1 to 3 Volts - assuming 3.3 Vcc - and an input amplitude range (Vinpp) of 0.5 to 1.3 VPP.

The customer settings are within these ranges and should not have issues.
