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
and the input swing lies within the V
PP
(DC) specification.
b. The MPC9456 is capable of driving 50Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated
transmission line to a termination voltage of V
TT
. Alternatively, the device drives up to two 50Ω series terminated transmission lines per
output.
c. Input pull-up / pull-down resistors influence input current.
d. ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.

.
b. The MPC9456 is functional up to an input and output clock frequency of 350 MHz and is characterized up to 250 MHz.
c. 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
and the input swing lies within the V
PP
(AC) specification.
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
pLH
- t

|.
