I = input, O = output, P = power supply, C = control.
Pin J7 (BGA), Pin 26 (LFCSP), and Pin 33 (LQFP) are dual function pins: I
down control function occurs whenever the state of the pin is changed from its original state at power-up.
For a full description of the 2-wire serial interface and its functionality, obtain documentation by contacting NDA from [e-mail].

Description
Differential Output Channel 1. Differential output of the
green data at 10× the pixel clock rate; supports TMDS logic level.
Differential Output Channel 0. Differential output of the blue
data at 10× the pixel clock rate; TMDS logic level.
Interrupt. Open drain. A 2 kΩ pull-up resistor to the
microcontroller I/O supply is recommended.
1.8 V Power Supply for TMDS Outputs.
1.8 V Power Supply for Digital and I/O Power Supply. These
pins supply power to the digital logic and I/Os. They should
be filtered and as quiet as possible.
1.8 V PLL Power Supply. The most sensitive portion of the
AD9889B is the clock generation circuitry. These pins provide
power to the clock PLL. The designer should provide quiet,
noise-free power to these pins.
Ground. The ground return for all circuitry on-chip. For best
practice, assemble the AD9889B on a single, solid ground
plane with careful attention given to ground current paths.
Digital Ground. The ground return for all circuitry on-chip.
For best practice, assemble the AD9889B on a single, solid

Serial Port Data I/O. This pin serves as the serial port data I/O
slave for register access. Supports CMOS logic levels from
1.8 V to 3.3 V.
Serial Port Data Clock. This pin serves as the serial port data
clock slave for register access. Supports CMOS logic levels
from 1.8 V to 3.3 V.
Serial Port Data I/O Master to HDCP Key EEPROM. Supports
CMOS logic levels from 1.8 V to 3.3 V.
Serial Port Data Clock Master to HDCP Key EEPROM. Supports
CMOS logic levels from 1.8 V to 3.3 V.
Serial Port Data I/O to Receiver. This pin serves as the master
to the DDC bus. Supports a 5 V CMOS logic level.
Serial Port Data Clock to Receiver. This pin serves as the
master clock for the DDC bus. Supports a 5 V CMOS logic level.
