DS90UH929-Q1: FPD-Link output jitter spec

Other Parts Discussed in Thread: ALP

Hi, E2E members

NOTE: This question is based on the following E2E.
e2e.ti.com/.../735163

I have questions about FPD-Link output jitter spec.
DS90UH929 datasheet says FPD-Link output jitter is 0.3UI(Typ).
Could you tell us a MAX spec?

Nao,

The 929 was only characterized with a TYP spec. If you are worried about the jitter margins matching the input of the deserializer, you can use the Margin Analysis Tool in ALP.

Please download the latest update fr ALP, and the margin analysis tab should be shown under the script folder for the device profile. You can find more info on how the margin analysis tool works here: e2e.ti.com/.../732296

Hi, Jonny

Thanks for reply.

927 datasheet has MAX spec.

Why doesn't 929 datasheet have MAX spec?

Nao,

There are several other devices such as the 949 that do not include a MAX spec either. For many of our devices now, we only spec TYP for the jitter since there are so many conditions that can affect some this characterization.

We do not have any plans as of right now to recharacterize the 929 for a MAX spec.
