Description
The STHDMI001A is a differential Single Pole Double Throw (SPDT) 2-to-1, low RON, bidirectional HDMI switch. It is designed to support HDMI/DVI television systems that produce superior high-definition image quality. The differential signal from the 2 HDMI ports is multiplexed through the switch to form a single output HDMI channel going to the HDMI receiver, while the deselected output goes to the high-Z (high impedance) state. It is designed for very low cross-talk, low bit-to-bit skew, high channel-tochannel noise isolation, and low I/O capacitance. This switch offers very little high-speed signal attenuation at the outputs, thus preserving the signal integrity necessary to pass stringent interference requirements. STHDMI001A provides the ability to switch a single source output to various display devices or switch video display devices between multiple sources. It reduces the overall BOM costs by eliminating the need for more costly multi input output controllers
