Description
The STHDMI001A is a differential Single Pole
Double Throw (SPDT) 2-to-1, low R_ON,
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
