DC Q
and the input swing lies within the V PP (DC) specification.
Input pull-up / pull-down resistors influence input current.
The MPC9443 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 (for
VCC=3.3V) or one 50 series terminated transmission line (for VCC=2.5V).
ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.
V PP
AC characteristics apply for parallel output termination of 50 to V TT .
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.
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.
t sk(LH, HL) includes both device skew referenced to the rising output edge and device skew referenced to the falling output edge.
Device-to-device skew referenced to the rising output edge.
Device-to-device skew referenced to the rising output edge or referenced to the falling output edge.
Output pulse skew is the absolute difference of the propagation delay times: | t pLH - t pHL |.
