Overview
The AD9889KSTZ-80 is an obsolete high-performance HDMI/DVI transmitter from Analog Devices. It operates at a clock frequency of up to 80 MHz, supporting video formats including 480i, 720p, and 1080i. The device features a single 1.8 V power supply with 3.3 V tolerant video/audio inputs and 5 V tolerant I2C/MPD I/Os. It integrates HDCP 1.1 compliance, an on-chip MPU for HDCP operations, and an I2C master for EDID reading. Audio capabilities include S/PDIF and 8-channel I2S support up to 192 kHz. The component is housed in an 80-lead Pb-free LQFP package.
Feature Summary
- Supports HDMI 1.1 and HDCP 1.1 protocols for secure content transmission
- Integrates programmable color space conversion and auto input format detection
- Handles digital audio via S/PDIF or 8-channel I2S without requiring an external audio master clock
- Includes on-chip I2C master for EDID reading and 5 V tolerant serial interfaces
Applications
- DVD players and recorders
- Digital set-top boxes
- AV receivers
- Digital cameras and camcorders
Procurement Notes
This component is officially classified as obsolete by the manufacturer. Verify current availability through authorized distributors or secondary markets. Confirm that the specific ordering suffix matches required pinout and packaging specifications. Ensure compatibility with existing system designs given the discontinued status.
Selection Notes
Select this component only if the design requires HDMI 1.1 and HDCP 1.1 compliance with an 80 MHz maximum clock rate. It is suitable for applications needing integrated HDCP handling and EDID management to reduce system complexity. Consider the 80-lead LQFP package constraints and single 1.8 V supply requirement during PCB layout.
Part Context
The AD9889KSTZ-80 belongs to the AD9889 family of high-definition multimedia interface transmitters. It is designed to bridge digital video sources to HDMI/DVI displays while ensuring content protection. The device simplifies system design by combining video processing, audio capture, and security functions into a single CMOS chip.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
