AD8195

Overview

The AD8195 is a buffered HDMI/DVI switch with equalized TMDS inputs and preemphasized outputs. It is designed to act as a signal-conditioning buffer, featuring three auxiliary channels and bidirectional DDC/CEC buffers to maintain signal integrity over long cable runs.

Why Choose This Part

It features fully buffered unidirectional TMDS channels with 50 Ohm on-chip terminations and low added jitter. The device simplifies design by integrating logic level translation for 3.3V and 5V domains and including a dedicated low-power shutdown mode that drops current consumption to approximately 1.8uA.

Applications

Getting Started

Engineers typically evaluate this part using the AD8195-EVALZ board, which allows for direct HDMI cable connection and performance testing. Ensure the 3.0V to 3.6V VDD supply is properly decoupled and that VTTI/VREF pins are configured according to the desired termination and preemphasis levels.
