Description
Pericom Semiconductor’s PI3HDMI412AD, active-drive switch
solution is targeted for high-resolution video networks that are
based on DVI/HDMI standards, and TMDS signal processing.
The PI3HDMI412AD is an active single TMDS channel to two
TMDS channe 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
2
C control, depending on the mode
select pin. The 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 data rate of 1.65Gbps provides a
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 of 8kV contact, which is required by many consumer
video networks today.
