Description

The STHDMI001A is a differential Single Pole

Double

Throw

(SPDT)

2-to-1,

low

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-to-

channel 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
