Description
The STHDMI002A is a differential Single Pole
Double Throw (SPDT) 2 to 1, low Ron,
bi-directional HDMI switch designed for advanced
TV applications supporting HDMI/DVI which
demand high definition superior image quality.
The differential signal from the 2 ports of HDMI is
multiplexed through the switch to form a single
output HDMI channel going to the HDMI receiver
while the unselected output goes to the high-Z
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. The switch offers very little or
practically no attenuation of the high-speed
signals at the outputs, thus preserving the signal
integrity to pass stringent requirements.
The STHDMI002A also includes the DDC as well
as the HPD line switching. The pin layout is
optimized for easy PCB routing to the HDMI
connector and HDMI receivers.
The maximum DVI/HDMI data rate of 1.65Gbps
provides the resolution required by the advanced
HDTV and PC graphics.
Advantages
STHDMI002A 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.
