OK, I'll bite. Some links to help you understand why it's not as simple as you think: http://en.wikipedia.org/wiki/Spdif Quote: "S/PDIF is used to transmit digital signals of a number of formats, the most common being the 48 kHz sample rate format used in DAT, and the 44.1 kHz format used in CD audio. In order to support both systems, as well as others that might be needed, the format has no defined data rate. Instead the data is sent using Biphase mark code, which has either one or two transitions for every bit, allowing the original word clock to be extracted from the signal itself." http://en.wikipedia.org/wiki/Biphase_mark_code http://www.maxim-ic.com/appnotes.cfm/appnote_number/1916/CMP/WP-34 Quote: "The SONET standard states that "Jitter is defined as the short-term variations of a digital signal's significant instants from their ideal positions in time. Significant instants could be (for example) the optimum sampling instants." The Fiber Channel standard simply defines jitter as "The deviation from the ideal timing of an event."
