PI3HDX414
HDMI 1.4b 1x4 Splitter for 3.4 Gbps Data Rate with Equalization
& Pre-emphasis
Pericom Semiconductor’s PI3HDX414, active-drive switch
solution is targeted for high-resolution video networks that are
based on HDMI/DVI standards, and TMDS signal processing.
The PI3HDX414 is an active single TMDS channel to four
TMDS channel Splitter and DeMux with Hi-Z outputs.
The device drives differential signals to four video display
units. It provides controllable output swing levels that can
be controlled through pin control or I2C control, depending
on the mode select pin. This solution also provides a unique
advanced pre-emphasis technique to increase rise and fall
times.
The maximum HDMI/DVI data rate of 3.4Gbps provides a
1920x1080 @60Hz resolution or 4K @30Hz required for 4K
HDTV and PC graphics products. For PC graphics application,
the device sits at the drivers side to switch between multiple
display units, such as PC LCD monitor, projector, TV, etc.
PI3HDX414 ensures transmitting high bandwidth video
streams from PC graphics source to end display units. It will
also provide enhanced robust ESD/EOS protection, which is
required by many consumer video networks today.
