Description
Pericom Semiconductor’s PI3HDMI412AD, active-drive switch
solution is targeted for high-resolution video networks that are
based on DVI/HDMI
The PI3HDMI412AD is an active single TMDS channel to two
TMDS channel DeMux with Hi-Z outputs. The device drives
differential signals to multiple video display units. It provides three
controllable output swing levels that can be controlled through
pin control or I
swing levels are 500mV, 700mV & 1000mV. This solution also
provides a unique advanced pre-emphasis technique to increase
rise and fall times which are reduced during transmission across
long distances.
The maximum DVI/HDMI
1920x1080 resolution required by the next Gen HDTV and PC
graphics products. Due to its active uni-directional feature, this
switch is de-signed for usage only for the video driver’s side. For
PC graphics application, the device sits at the driver’s side to
switch between multiple display units, such as PC LCD monitor,
projector, TV, etc.
PI3HDMI412AD is the industry’s fi rst active DVI/HDMI
compliant switch, which ensures transmitting high bandwidth
video streams from PC graphics source to end display units.
PI3HDMI412AD will also provide enhanced robust ESD/EOS
protection, which is required by many consumer video networks
today.
