CDCLVC1102: Can we connect HCMOS output of clock oscillator to clock input of CDCLVC1102 chip

Part Number: CDCLVC1102

Hi There,

We are planning to interface HCMOS output of OCXO clock oscillator to CLKIN of CDCLVC1102 LVCMOS buffer chip. Can we do this?

HCMOS output logic level is 90% VDD (it is 2.97V as we operate at 3.3V power) and VOL (max) is 10% of VDDD=0.33V.  Whereas clock buffer has Vih min of 2.25V and Vil max of 1.05V. 

So it looks okay to interface as per my understanding. But i am not sure whether any other points to be considered to connect HCMOS output to LVCMOS input? Please share your comments.

Regards,

Murugan
