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 DS90UB914A-Q1 Deserializer than the
DSDS90UB913A-Q1 Serializer. The pins must be pulled to VDD (1.8V, not VDDIO) with a 10 kΩ resistor and two
pull down resistors (R_ID0 and R_ID1) of the recommended value to set the physical device address. The
recommended maximum resistor tolerance is 1%.
