Overview
The AD8190ACPZ-R7, produced by Analog Devices Inc., is a 2:1 HDMI/DVI switch with equalization. This component is designed to handle high-speed video signals, making it ideal for systems that require reliable transmission over long cable runs. The AD8190 supports data rates up to 1.65 Gbps, enabling resolutions such as UXGA (1600 × 1200) for DVI and 1080p for HDMI. It features equalized TMDS inputs and pre-emphasized TMDS outputs, which are crucial for maintaining signal integrity over extended cable lengths.
