  • RE: LMH5401: Can VOCM be floated/bypassed for AC-coupled single mid-supply design

    Resolved
    Hello KJ, You should always drive the VOCM pin for the LMH5401; section 8.3.4 of the datasheet should be followed. Please set VOCM pin to 2.5V (mid-supply) externally, you can reference the LMH5401EVM User Guide: https://www.ti.com/lit/ug/slou401a/slou401a…

  • RE: TIDA-01350: TIDA-01350

    Hello Wyatt, LMH5401 is a good choice for the application. For the reference design, TIDA-01350, you might have to include feedback capacitors depending on your parasitics + photodiode capacitor on the first stage to compensate for the capacitance the…

  • RE: LMH5401: Active Termination

    Resolved
    Hi Apurva, I think it would be tough to maintain the maximum voltage of 5.2-5.5Vpp differential in the 1-2GHz range using the LMH5401, as you would start getting into compression issues at these frequencies. I would recommend you to evaluate the LMH5401…
