 Dear Sir,

Is  the DS90UB933 power over coax  circuit difference with DS90UB913A’? can we keep DS90UB913A/4A  POC circuit and just switch the ICs to DS90UB933 /4? Thanks,

    Hello,

    PoC filtering/ circuitry is determined from both the FCC (Forward Channel) frequency as well as the BCC (Back Channel) frequency. If you are operating both pairs of devices at the same speeds then the same PoC filtering should be fine. However, if you are utilizing the higher speeds available with the 933/4 then you will need to adjust your filtering accordingly. Please refer to the user's guide for the appropriate EVMs for suggested PoC filtering. www.ti.com/.../snlu210a.pdf
