DS90UB960-Q1: VPOC noise

DS90UB960-Q1: POC impedance

Hi,

   POC use several inductors to provide a high impedance over a wide frequency range. Could you tell me what is the minimum impedance that should be reached up over the whole bandwidth? Or it is different at different frequency point?

    Hello Zehui,

    our recommendation is to maintain a 1Kohm Impedance for the complete frequency range. Please note that this is not a requirement but only recommendation. Our requirement is to fulfill the Channel Specs (Insertion Loss, Return Loss)
