a. The MPC9446 is capable of driving 50
transmission lines on the incident edge. Each output drives one 50
parallel terminated transmission
line to a termination voltage of V
TT
. Alternatively, the device drives up to two 50
series terminated transmission lines per output.
b. Input pull-up / pull-down resistors influence input current.
c. I
CCQ
is the DC current consumption of the device with all outputs open and the input in its default state or open.

.
b. AC specifications are design targets, final specification is pending device characterization.
c. The MPC9446 is functional up to an input and output clock frequency of 350 MHz and is characterized up to 250 MHz.
d. 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
pulse width, output duty cycle and maximum frequency specifications.
e. Output pulse skew is the absolute difference of the propagation delay times: | t
