AD8197BASTZ-RL

Overview

The AD8197BASTZ-RL is a 4:1 HDMI/DVI switch with equalization manufactured by Analog Devices Inc. It operates in a 100-lead LQFP package and supports data rates up to 2.25 Gbps. The device features four TMDS channels per link, enabling HDMI 1.3-compliant receiver functionality. It includes input cable equalizers allowing the use of long cables (over 20 meters at 2.25 Gbps) and pre-emphasized outputs. The component supports pixel clocks from 25 MHz to 225 MHz and accommodates deep color formats.

Feature Summary

• Features fully buffered unidirectional high-speed inputs and outputs with switchable on-chip terminations.
• Includes an input cable equalizer to compensate for signal loss over long HDMI cable runs.
• Provides pre-emphasized outputs to maintain signal integrity across transmission lines.
• Supports auxiliary channel switching for DDC bus and additional control signals.

Applications

• Multiple input displays
• Projectors
• A/V receivers
• Set-top boxes
• Advanced television (HDTV) sets

Procurement Notes

Verify the specific ordering suffix RL against current manufacturer documentation to confirm reel packaging specifications. Confirm availability status as supply conditions may vary. Ensure compatibility with I2C serial or parallel control interfaces required by the system design. Validate that the 100-lead LQFP footprint matches the PCB layout constraints.

Selection Notes

Select this component for systems requiring switching between four HDMI or DVI sources to a single display output. It is suitable for applications needing integrated equalization to support extended cable lengths without external amplifiers. Consider the power dissipation characteristics when designing thermal management solutions for the LQFP package.

Part Context

This part belongs to the AD8197B series, which serves as a pin-to-pin compatible replacement for the AD8197A. It is designed to meet HDMI 1.3 standards and supports dual-link configurations when two devices are used together. The series focuses on providing robust signal switching with minimal added jitter for high-definition video applications.

Replacement Considerations

The AD8197B is explicitly documented as a pin-to-pin compatible replacement for the AD8197A. Verify that any substitute maintains the same 100-lead LQFP package dimensions and electrical interface requirements.
