(1) Total latency for the channel link chipset is a function of clock period and gate delays through the transmitter (TCCD) and receiver (RCCD). The total latency for the DS90CR285 transmitter and DS90CR286AT-Q1 receiver is: (T + TCCD) + (2*T + RCCD), where T = Clock period. If another transmitter is used, the alternative transmitter's TCCD must be used to calculate total latency.
