LMH0202_0606 Datasheet, PDF (4/6 Pages) National Semiconductor (TI) – Dual SMPTE 292M / 259M Serial Digital Cable Driver

Note 5: Maximum I_CC is measured at V_CC = +3.465V and T_A = +70˚C.
Note 6: Specification is guaranteed by characterization and verified by test.
Note 7: Output return loss is dependent on board design. The LMH0202 meets this specification on the SD202 evaluation board from 5MHz to 1.5GHz.

Device Operation
INPUT INTERFACING
The LMH0202 accepts either differential or single-ended
input. The inputs are self-biased, allowing for simple AC or
DC coupling. DC-coupled inputs must be kept within the
specified common-mode range. SDI and SDI are self-biased
at approximately 2.1V with V_CC = 3.3V. Figure 1 shows the
differential input stage for SDI and SDI.
