2.1.2.1 SDI_IN1 Selected

  1. Connect the LMH1239EVM to the system under test.
    1. The input signal on J3 can be connected to a video signal generator over a 75Ω coax cable.
    2. The output signals on J20, J21, J23 and J25 can be connected with matched 100Ω differential cables to a high-speed scope to view the output eye diagram. Alternatively, this 100Ω output can be used as the source for another SDI cable driver.
    3. The output signal on J32 can be connected with 75Ω coax cable to a video pattern analyzer.
