7.5.5 IDX Address Decoder on the Serializer
The IDX pin on the serializer is used to decode and set the physical slave address of the serializer (I2C only) to allow up to five devices on the bus connected to the serializer using only a single pin. The pin sets one of the 4 possible addresses for each serializer device. The pin must be pulled to V(VDD_n) (1.8 V, not V(VDDIO)) with a resistor, R3, and a pulldown resistor R4. Suggested resistor values are given in Table 7-6. The recommended maximum resistor tolerance is 1%. Other resistor values can be used as long as the ratio is met under all conditions.
