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 3 shows the differential input stage for SDI and SDI. VCC SDI SDI VCC 5 k: 10 k: 80: 10 k: 10 k: Figure 3. Differential Input Stage for SDI and SDI. OUTPUT INTERFACING The LMH0002 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. OUTPUT SLEW RATE CONTROL The LMH0002 output rise and fall times are selectable for either SMPTE 259M or SMPTE 292M compliance via the SD/HD pin. For slower rise and fall times, or SMPTE 259M compliance, SD/HD is set high. For faster rise and fall times, or SMPTE 292M compliance, SD/HD is set low. REPLACING THE GENNUM GS1528, GS1528A, and GS1578A The LMH0002MA is form-fit-function compatible with the Gennum GS1528 and GS1528A. The LMH0002SQ is form-fit-function compatible with the Gennum GS1578A.
