Wanting to use the LMK00334RTVRQ1 as a clock mux/buffer for PCIe 2.0.

What is the 2.0 additive jitter max and typical for the high and low frequency bands with an HCSL clock output?

Hi Jack,

Please take a look at this blog post: https://e2e.ti.com/blogs_/b/analogwire/archive/2014/03/28/how-to-optimize-clock-distribution-in-pcie-applications

Table 4 is of particular interest.

Kind regards,

Hello Lane,

Thank you for the blog post as it was helpful to find the typical additive jitter. Do you have any information on the 2.0 jitter max? I cannot find that information on the blog post.

Thanks,

Jack
