a.

VCMR (DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the VCMR range

and the input swing lies within the VPP (DC) specification.

b.

Input pull-up / pull-down resistors influence input current.

c.

The MPC9456 is capable of driving 50

Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated

transmission line to a termination voltage of VTT. Alternatively, the device drives up to two 50Ω series terminated transmission lines.

d.

ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.

a.

AC characteristics apply for parallel output termination of 50

Ω to VTT.

b.

The MPC9456 is functional up to an input and output clock frequency of 350 MHz and is characterized up to 250 MHz.

c.

VCMR (AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the VCMR range

and the input swing lies within the VPP (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: | tpLH - tpHL |.
