ID[x] Address Decoder on the Deserializer

The IDx[0] and IDx[1] pins on the Deserializer are used to decode and set the physical slave address of the

Deserializer (I2C only) to allow up to 16 devices on the bus using only two pins. The pins set one of 16 possible

addresses for each Deserializer device. As there will be more Deserializer devices connected on the same board

than Serializers, more I2C device addresses have been defined for the DS90UB914Q Deserializer than the

DSDS90UB913Q Serializer. The pins must be pulled to VDD (1.8V, not VDDIO) with a 10 kΩ resistor and two

pull down resistors (RID0 and RID1) of the recommended value to set the physical device address. The

recommended maximum resistor tolerance is 1%.
