LMH0318: LMH0318

Part Number: LMH0318

Hello,

Do you have recommendation for unused channel inputs, can we left them floating or is it better to ground them with 50 Ohm?

Best regards,

Tristan

  • Hi Tristan,

    It is preferred to AC couple and then 50-ohm to ground. Un-used input would have its signal detect off and this powers down CDR if this input is selected. It is a good design practice to terminate un-used inputs to prevent any potential cross coupling.
