Serializer DS90UB947 VDDIO connect 1.8 V level, DeSerializer DS90UB948 VDDIO connect 3.3 V level , GPIO control from remote Serializer, DeSerializer DS90UB948 GPIO level is 1.8V ；
why 948 GPIO output level consistent with 947 VDDIO , not consistent with the 948 VDDIO ？
Note : To achieve the function of " GPIO control from remote Serializer, output level consistent with 948 VDDIO "
