with Equalization & Pre-emphasis
Features
General Description
Pericom Semiconductor’s PI3HDX412BD, active-drive
ꢀySupport up to 3.4Gbps TMDS Serial Link Compliant
switch solution is targeted for high-resolution video net-
with HDMI 1.4b requirement
TM
works that are based on HDMI /DVI standards, and
ꢀyHDMI 1-to-2 Splitter or 1-to-2 DeMux with
Equalization & Pre-emphasis up to 340 MHz Clock
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.
ꢀyAC or DC Coupled Differential Signaling Input
ꢀyConfigurableTMDSOutputSignalwithPortSelection,
Pre-emphasis, Voltage Swing, Slew Rate Control
ꢀySupport Squelch Mode with Built-in Clock detector
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.

ꢀyESD Protection on I/O pins to connector: 8KV Contact
per IEC6100-4-2 and 2KV HBM
TM
The maximum HDMI /DVI data rate of 3.4Gbps provides
ꢀySupply Voltage: 3.3V
ꢀyIndustrial Temperature Range: -40 C to 85 C
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.

ꢀyPackaging (Pb-free & Green): 56-contact TQFN
(ZB56)
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.
