  • Page 58: Timing

    Configuring Your GV Node Timing Timing Clean vertically-accurate switches between sources in the fabric module require the sources to be time-aligned. There are two signal entry planes in GV Node - the SDI inputs on the XIO-4901 cards, and the IP inputs on the aggregation ports. Generally speaking, it is not possible to ensure that signals arriving at both of these are time-aligned, so switching between an SDI input and and IP input will almost certainly be a dirty switch.
