NAME

FUNCTION

INTOUT

A/V Status Register Interrupt Output. Indicates new data in the A/V status registers. INTOUT is reset

when the A/V status registers are read.

GPI

General-Purpose Input with Internal Pulldown to EP. The serializer GPO (or INT) output follows GPI.

I2CSEL

I2C Select. Control channel interface protocol select input with internal pulldown to EP. Set I2CSEL =

high to select I2C interface. Set I2CSEL = low to select UART interface.

GPIO0

Open-Drain, General-Purpose Input/Output, with Internal 60kΩ Pullup to IOVDD

BWS

Three-Level Bus Width Select Input. Set BWS to the same level on both sides of the serial link. Set

BWS = low, with 6kΩ (max) pulldown for 24-bit mode. Set BWS = high, with 6kΩ (max) pullup to

IOVDD for 32-bit mode. Set BWS = open for high-bandwidth mode.

6, 47

AVDD3

3.3V Analog Power Supply. Bypass AVDD3 to EP with 0.1µF and 0.001µF capacitors as close as

possible to the device with the smaller capacitor closest to AVDD3.

IN+

Noninverting Coax/Twisted-Pair Serial Input

IN-

Inverting Coax/Twisted-Pair Serial Input
