AD9389
Pin Mnemonic
Description
POWER SUPPLY
DVDD
AVDD
PVDD
GND
Main Power Supply. These pins supply power to the main elements of the circuit. They should be filtered and as
quiet as possible.
Output Power Supply.
Clock Generator Power Supply. The most sensitive portion of the AD9389 is the clock generation circuitry. These
pins provide power to the clock PLL (phase-locked loop) and help the user design for optimal performance. The
designer should provide quiet, noise-free power to these pins.
Ground. The ground return for all circuitry on-chip. It is recommended that the AD9389 be assembled on a single
solid ground plane, with careful attention given to ground current paths.
I2C ADDRESSES
The SDA/SCL programming address can be 0x72 or 0x7A based on whether the PD/A0 pin is pulled high (10 kΩ resistor = 0x7A) or
pulled low (10 kΩ resistor = 0x72).
The EDID EEPROM on the receiver is expected to have an address of 0xA0.

Format
Hexadecimal (base-16) numbers are represented using the C language notation, preceded by 0x.
Binary (base-2) numbers are represented using the C language notation, preceded by 0b.
Decimal (base-10) numbers are represented using no additional prefixes or suffixes.
Bits are numbered in little-endian format, that is, the least significant bit (LSB) of a byte or word is referred to as Bit 0.
