PI3HDMI336
3:1 ActiveEye™ HDMI™ Switch with I²C Control & ARC Transmitter
Features
Description
ÎÎHDMI 1.4 compliant with fast video switch among each
ports
ÎÎI²C control 3:1 HDMI active switch Mux with DC coupled
or AC coupled Dual mode DisplayPort signals
àà Output will maintain its DC coupled, current-
steering
àà TMDS compliance input can be AC coupled video or
DC coupled
ÎÎ2.5Gbps data rate for TMDS clock up to 250MHz
PI3HDMI336 is an I²C configurable active switch using
Pericom’s new ActiveEye^TM technology to achieve optimized sig-
nal integrity for cable or on board transmission.
Through I²C interface, system designer can easily program and
adjust equalization, emphasis and output swing settings.
With integrated DDC channel Mux, Hot Plug Detection
De-Mux, cable plug-unplug detection and HDMI 1.4 ARC
transmitter, PI3HDMI336 saves GPIO control pins, provides
optimized trace routing, and reduces BOM cost.
ÎÎSupport up to 36-bits per pixel Deep Color^TM modes
Programmable TMDS input termination settings helps designers
ÎÎProgrammable equalizer, emphasis and amplitude settings
to achieve optimized HDMI signal integrity
to avoid the compatibility issue caused by non standard HDMI
source.
ÎÎIntegrated selectable DDC active/ passive switch to connect
DDC path
ÎÎIdle clock detection function for output squelch
Programmable output termination setting supports double ter-
mination option between PI3HDMI336 and the HDMI receiver
chip. This feature minimizes the reflection caused by improper
impedance matching and reduces the signal jitter.
ÎÎProgrammable TMDS termination control
PI3HDMI336 is HDMI 1.4 compatible with backward compat-
àà TMDS input pull-up 50 Ohm termination, pull-down ibility to the DVI 1.0 standard and can be used for the DP++ ap-
>120K Ohm resistor when switch is deselected
plication devices.
àà Double terminated TMDS output
ÎÎIntegrated ESD protection on I/O pins to connector
àà 8KV contact per IEC61000-4-2, level 3
