3:1 Active HDMI 1.3 Compatible Switch with Optimized

Description

Pericom Semiconductor’s PI3HDMI341ART 3:1 active switch

circuit is targeted for high-resolution video networks that are

based on DVI/HDMI standards and TMDS signal processing.

The PI3HDMI341ART is an active 3 TMDS to 1 TMDS 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. This solution also provides a unique

advanced pre-emphasis technique to increase rise and fall times

which are reduced during transmission across long distances.

Each complete HDMI/DVI channel also has slower speed, side

band signals, that are required to be switched. Pericom’s solution

provides a complete solution by integrating the side band switch

together with the high speed switch in a single solution. Using

Equalization at the input of each of the high speed channels,

Pericom can successfully eliminate deterministic jitter caused by

long cables from the source to the sink. The elimination of the

deterministic jitter allows the user to use much longer cables (up

to 25 meters).

The maximum DVI/HDMI Bandwidth of 2.5 Gbps provides 12-

bit deep color support, which is offered by HDMI revision 1.3.

Due to its active uni-directional feature, this switch is designed

for usage only for the video receiver’s side. For consumer video

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

multiple video components, such as PC, DVD, STB, D-VHS,

etc. The PI3HDMI341ART is the industry’s first active DVI/

HDMI switch compatible with HDMI 1.1, 1.2, and 1.3 which

ensures transmitting high-bandwidth video streams from video

components to the display unit. The PI3HDMI341ART also

provides enhanced robust ESD/EOS protection of 8kV, which is

required by many consumer video networks today.

The Optimized Equalization provides the user a single optimal

setting that can provide HDMI compliance for all cable lengths:

1meter to 20meters and color depths of 8bit/ch, or 12bit/ch.

Pericom also offers the abiility to fine tune the equalization

settings in situations where cable length is known. For example,

if 25meter cable length is required, Pericom's solution can be

adjusted to 16dB EQ to accept 25metere cable length.
