DEVICE OPERATION
INPUT INTERFACING
The LMH0001 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 selfbiased at approximately 2.1V with VCC = 3.3V. Figure 2 shows the differential input stage for SDI and SDI.

Figure 2. Differential Input Stage for SDI and SDI.
OUTPUT INTERFACING
The LMH0001 uses current mode outputs. Single-ended output levels are 800 mVP-P into 75Ω AC-coupled
coaxial cable (with RREF = 750Ω). Output level is controlled by the value of the RREF resistor connected between
the RREF pin and VCC.
The RREF resistor should be placed as close as possible to the RREF pin. In addition, the copper in the plane
layers below the RREF network should be removed to minimize parasitic capacitance.
