Video Processing datasheet and documents for STHDMI001ATTR
Video Processing Overview
The STHDMI001ATTR is a differential Single Pole Double Throw (SPDT) 2-to-1 HDMI switch manufactured by STMicroelectronics. It supports HDMI v1.1 and DVI v1.0 standards with a data rate of 1.65 Gbps per channel. The device operates on a 3.0V to 3.6V supply, features a typical ON resistance of 5.5 Ω, and consumes 20 µA in low power mode. It provides ESD protection of ±2 kV HBM and functions within a -40°C to 85°C temperature range.
Video Processing Feature Summary
- Routes physical layer signals for high bandwidth digital video using Transition Minimized Differential Signaling (TMDS).
- Multiplexes differential outputs from two video sources to one common display output while maintaining signal integrity.
- Integrates SPDT-type switches for three differential data TMDS channels and one differential clock channel.
