PI3HDX412BD
HDMI 1.4b 1:2 Splitter/Demux for 3.4Gbps Data Rate
with Equalization & Pre-emphasis
Pericom Semiconductor’s PI3HDX412BD, active-drive switch
solution is targeted for high-resolution video networks that
are based on HDMITM/DVI standards, and TMDS signal
processing.
The PI3HDX412BD is an active single TMDS channel to
two TMDS channel Splitter and DeMux with Hi-Z outputs.
The device drives differential signals to multiple 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 HDMITM/DVI data rate of 3.4Gbps provides
a 1920x1080 @ 60Hz resolution or 4K @30Hz required for
4K HDTV and PC graphics products. Due to its active unidirectional feature, this switch is designed 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.
PI3HDX412BD 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.
