Note: 1. 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.
2. Input pull-up / pull-down resistors influence input current.
3. The ASM2I99448 is capable of driving 50ꢀ transmission lines on the incident edge. Each output drives one 50ꢀ parallel terminated transmission line to
a termination voltage of VTT. Alternatively, the device drives up to two 50ꢀ series terminated transmission lines (for VCC=3.3V) or one 50ꢀ series
terminated transmission line (for VCC=2.5V).
4. ICCQ is the DC current consumption of the device with all outputs open and the input in its default state or open.
