Symbol
1. The MPC9446 is capable of driving 50 Ω transmission lines on the incident edge. Each output drives one 50 Ω parallel terminated
2. Input pull-up / pull-down resistors influence input current.
3. I
Symbol
1. AC characteristics apply for parallel output termination of 50 Ω to V
2. The MPC9446 is functional up to an input and output clock frequency of 350 MHz and is characterized up to 250 MHz.
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 t
