a.

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

b.

The MPC9443 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

(for VCC=3.3V) or one 50

Ω series terminated transmission line (for VCC=2.5V).

c.

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.

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.

This table only specifies AC parameter im mixed voltage supply conditions that vary from the corresponding AC tables. All other

parameters, see the 3.3V (for 3.3V outputs) or 2.5V AC table (for 2.5V outputs).

c.

tsk(LH, HL) includes both device skew referenced to the rising output edge and device skew referenced to the falling output edge.

d.

Output pulse skew is the absolute difference of the propagation delay times: | tpLH - tpHL |.
