Hi team,

How much is the random jitter (1 sigma) of the forward channel output?

We collect information to simulate.

Best regards,

Hello Tomoaki-san,

please refer to the data sheet page 10. There you have the Total jitter value at the forward channel output.

Hi Hamzeh-san.

Thank you for your reply.

I know that there is a total jitter in data sheet.

But, it is only typical value.

Our goal is to determine the certainty of boards and cables from simulations under worst conditions.

I understand that random jitter is usually expressed as sigma because it is infinite.

It does not have to be a guaranteed value, but is there any actual measurement data or variations to be used as a reference?

Best regards,

Tomoaki Yoshida

Hello Tomoaki-san,

we do not really specify randon jitter, we only specify total jitter in terms of UI.

The max measured Total jitter across Temp and voltage = 0.245 UI.
