Description

Pericom Semiconductor’s PI3HDMI421AR 2:1 active mux circuit

is targeted for high-resolution video networks that are based

on DVI/HDMI standards, and TMDS signal processing. The

PI3HDMI421AR is an active 2 TMDS to 1 TMDS mux receiver

switch with Hi-Z outputs. The device receives differential signals

from selected video components and drives the video display unit.

It provides three controllable output swings that can be controlled

through a single bit. The allowable output swings are 500mV,

750mV and 1000mV.

advanced pre-emphasis technique to increase rise and fall times

which are reduced during transmission across long distances.

The maximum DVI/HDMI Bandwidth of 2.5Gbps provides

1920x1080 resolution with 12-bit/channel color depths required

by the next Gen HDTV and PC graphics. For consumer video

networks, the device sits at the receiver’s side to switch between

multiple video components. PI3HDMI421AR is the industry’s

ﬁ rst active DVI/HDMI switch compatible with HDMI rev. 1.3,

which ensures transmitting high bandwidth video streams from

video components to the display unit.

The Optimized Equalization provides the user a single optimal

setting that can provide HDMI compliance for all cable lengths:

2meter, 10meter, 15meter, and 20 meter. Pericom also offers the

ability to ﬁ ne tune the equalization settings in situations where

cable length is known.
