SN74LVC1G125 - Jitter and Phase Noise Figures?

Other Parts Discussed in Thread: SN74LVC1G125

Hello All,

Is there any test data for the SN74LVC1G125 regarding jitter and phase noise figures?

I have looked at some test signals @ 10MHz - looks OK - but was wondering if TI has any test data for
jitter and phase noise. I am considering using for some 10MHz clock signals - single ended - and wanted
to know if TI has any of these figures.

The part is nice and small - good for compact designs.

Here is an example of the circuit I am asking about:

Thanks In Advance,

We do not have this information for standard logic devices. Our clock driver devices would have this type of information.

Typical jitter for the LVC family is 40ps worse case.

If the clock signal is coming from a crystal that is not square wave you will also need schmitt trigger input.

you might consider SN74LVC1404 SN74LVC1GX04

Here is an appnote that may also help http://www.ti.com/lit/pdf/szza043

Hello Chris,

The signal source is LVCMOS square wave compatible.

Thanks for the other suggestions and pointing out the app note.

I see TI does have some ECL. Do you have any ECL suggestions?

Thanks,
johnw

Sorry

I dont know much about ECL.
