Pericom Semiconductor’s PI3HDX412BD, active-drive
switch solution is targeted for high-resolution video net-
works 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 con-
trolled 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 uni-
directional 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 dis-
play 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.

Description
Input Port. TMDS Clock and Data Input pins. When Input Termination
Resistor (Rt = 50 Ohm) tied to VDD or GND, Rpd=200 kOhm shall be
"OFF" state.
I2C registers can control Rt and Rpd ON/OFF state.
Output Port 1. TMDS Clock and Data Output pins. ROUT_SEL pin en-
ables Output Termination Resistor (Rout=50 Ohm).
Output Port 2. TMDS Clock and Data Output pins. ROUT_SEL pin en-
ables Output Termination Resistor (Rout=50 Ohm).
Note: In TMDS Data and Clock Differential Pair, the polarity +/- (or P/N) of each pair can use interchangeably. When input TMDS Input Clock polarity +/-
pin swaps, output TMDS Clock of port 1 and port 2 shall swapped accordingly.
