SN74AUP1T58 / about additive jitter (fclk=66MHz)

Wei - san,

Thank you for the reply. I would like to know the following formula for SN74AUP1T58(fclk=66MHz).

Would you please provide the information ?

Best Regards,

Kato-San,

We dont have this spec for the SN74AUP1T58. The closest spec will be a propagation delay skew.

Parts like LMK00105, which specifically distrubute the clock signals with low jitter,will have jitter charactrized at different frequencies. This will also be an electrical spec.

If you explain your application and need for this spec, I can assist you further.

Thanks

Hi Jennifer -san,

Thank you for the reply. We have not information for this spec. we are considering replacing clock devices for cost reduction.

Hi Kato-san

The magnitude of the time difference between the high-to-low (tPHL) and the low-to-high (tPLH) propagation delays when a single switching input causes one or more outputs to switch is the "pulse skew". There are several skew specifications, this is the one that I feel might be applicable for your application. Since both tPHL and tPLH are same for this part, we have to assume that the delay is insignificant.

Unfortunately, only the clock buffers will have the jitter specifications. If required, I can check for cost effective options in that group.

Thanks
