Hi Expert,

How many I2C/ GPIO/ power can be used in DS90UB953/ DS90UB954? Does it support POC?

    Hi Far, 

    There is one I2C port on both the UB954 and UB953 supporting fast mode. 

    Seven GPIO pins are available on the UB954 and four GPIO pins on the UB953. 

    PoC is supported for the UB954 and UB953. Information on PoC can be found in Section 8.1.2 Power over Coax in the UB954 and UB953 Datasheet. The Application Note "Power-over-Coax Design Guidelines for DS90UB953-Q1" SNLA272 can also be used as a reference. 

    Best,

    Zoe
