Note: 1 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.
2 Input pull-up / pull-down resistors influence input current.
3 The ASM2I99456 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.
4 I
CCQ
is the DC current consumption of the device with all outputs open and the input in its default state or open
