AD9889ABBCZ-80

Overview

The AD9889ABBCZ-80 is an HDMI v1.2a and DVI v1.0 transmitter supporting HDCP 1.1 encryption. It operates at a clock frequency of 80 MHz, accommodating video resolutions from 480i to 720p/1080i and XGA at 75 Hz. The device utilizes a single 1.8 V power supply with digital inputs accepting logic levels between 1.8 V and 3.3 V. Audio capabilities include S/PDIF and 8-channel I2S up to 192 kHz. It features an on-chip microprocessor for HDCP and EDID management via I2C master interfaces. The component is housed in a 76-ball CSP_BGA package.

Feature Summary

• Integrated high-definition multimedia interface transmitter compatible with HDMI v1.2a, DVI v1.0, and HDCP 1.1 protocols.
• On-chip microprocessor handles HDCP operations and EDID reading through I2C master functionality.
• Supports dual audio input formats including standard S/PDIF and 8-channel uncompressed LPCM I2S.
• Features 5 V tolerant I2C and hot plug detect I/Os requiring no additional external components.

Applications

• DVD players and recorders
• Digital set-top boxes
• A/V receivers
• Digital cameras and camcorders
• HDMI repeater/splitter

Procurement Notes

Verify the specific ordering suffix and package option against current manufacturer documentation before procurement. Confirm that the required temperature range aligns with the -25°C to +90°C specification. Ensure system designs account for the 76-ball CSP_BGA footprint requirements. Check for any product change notices or end-of-life announcements regarding this part number.

Selection Notes

Select this component for applications requiring integrated HDCP 1.1 compliance without external security controllers. The single 1.8 V supply simplifies power distribution compared to multi-voltage alternatives. Verify compatibility with source devices providing 1.8 V to 3.3 V logic level video and audio signals. Consider the 76-ball BGA package constraints during PCB layout planning.

Part Context

This transmitter belongs to the AD9889A family, designed for high-performance consumer electronics. It integrates video processing, audio handling, and security functions into a single CMOS chip. The device reduces system complexity by embedding the necessary control logic for display communication and content protection directly on the silicon die.

Replacement Considerations

The AD9889ABBCZRL-80 is a listed alternative within the same family, sharing identical electrical specifications and pinout configuration while differing only in packaging format.
