MPC9448
a. AC characteristics apply for parallel output termination of 50 to V TT .
b. V CMR (AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the V CMR range
c. 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
d. Output pulse skew is the absolute difference of the propagation delay times: | t pLH - t pHL |.
a. V CMR (DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the V CMR range
b. Input pull-up / pull-down resistors influence input current.
c. The MPC9448 is capable of driving 50 transmission lines on the incident edge. Each output drives one 50 parallel terminated
d. I CCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.
