9 / 18 page 9 www.fairchildsemi.com Receiver AC Electrical Characteristics (66MHz) Note 20: For the receiver with falling-edge strobe, the definition of setup/hold time will be slightly different from the one with rising-edge strobe. The clock ref- erence point is the time when the clock falling edge passes through 2V. For hold time tRHRC, the clock reference point is the time when falling edge passes through 0.8V. Note 21: Total channel latency from Sewrializer to deserializer is (T tTCCD) (2*T tRCCD). There is the clock period. Note 22: Receiver skew margin is defined as the valid sampling window after considering potential setup/hold time and minimum/maximum bit position.
