Description
Pericom Semiconductor’s PI3HDMI411AD, active-drive switch
solution is targeted for high-resolution video networks that are
based on DVI/HDMI standards, and TMDS signal processing.
The PI3HDMI411AD is an active single TMDS channel re-driver
with Hi-Z outputs. The device drives differential signals with
enhanced signal integrity to video display units. It provides three
controllable output swing levels that can be controlled through
pin control or I2C 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 2.5Gbps provides a
1920x1080 resolution required w/ 12 bit/channel color depth, by
the next Gen HDTV and PC graphics products.
PI3HDMI411AD is the industry’s rst active DVI/HDMI
compliant switch, which ensures transmitting high bandwidth
video streams from PC graphics source to end display units.
The Optimized Equalization provides the user a single optimal
setting that can provide HDMI compliance for all cable lengths:
2meter, 10meter, 15meter, and 20 meter. Pericom also offers the
ability to ne tune the equalization settings in situations where
cable length is known.
