Jitter Reference?[edit]

Good article, that typically seems to cover the issue at an appropriately generic level. But I'm concerned about the inclusion of jitter values for a few reasons.

First, jitter is a fairly detailed, low-level topic, that really digs into the specifics of a SerDes implementation. This contrasts with the overall tone of the article, which is typically high level. I don't have a problem with the overall tone of the article, but mentioning jitter would only seem appropriate if the article was more technical overall.

Second, if jitter values are to be included, I'm concerned about how specific the values are. The article specifically refers to "high speed" implementations, and certainly that is typically the use case (USB, Inter-Processor Communications, D-Phy, M-Phy, etc.). But by definition, a UART is a SerDes, which can be quite slow. And a UART running at ~1kbps can certainly handle more jitter than an M-Phy running at ~5Gbps. It would seem more appropriate to spec the jitter as a function of the bit rate.

Third, raising the issue of jitter can also raise the issue of jitter characterization (random vs deterministic, or total). I assume the provided values are total jitter, but it would be good to note that. It might also be appropriate to provide a link to a Wikipedia page on jitter (haven't looked for that yet).

In one place in the article it's capitalized SerDes, in another SERDES (as if it were an acronym). Why is it capitalized at all? We don't capitalize radar or modem. Rsmoore (talk) 06:55, 19 September 2008 (UTC)

Wikipedia documents how these terms are used by the people who use them. Technical terms like SerDes used almost exclusively by engineers can have interesting grammar. When a word enters common usage, the grammar for it often changes. --Kvng (talk) 13:05, 23 April 2011 (UTC)

Tx frequency[edit]

What is the "Tx frequency"? An explanation could be added.
