1. AC characteristics apply for parallel output termination of 50 Ω to V
2. V
3. Violation of the 1.0 ns maximum input rise and fall time limit will affect the device propagation delay, device-to-device skew, reference input
4. Output pulse skew is the absolute difference of the propagation delay times: | t
1. V
2. Input pull-up / pull-down resistors influence input current.
3. The MPC9448 is capable of driving 50 Ω transmission lines on the incident edge. Each output drives one 50 Ω parallel terminated
