Description

Pericom Semiconductor’s PI3HDMI201 2:1 active switch circuit

is targeted for high-resolution video networks that are based

on DVI/HDMI

PI3HDMI201 is an active 2 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. 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

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

bit deep color

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 PI3HDMI201 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

for all cable lengths: 1meter to 20meters and color depths of 8bit/

ch, or 12bit/ch.

Pericom also offers the ability to ﬁ ne 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.

Equalization for Enhanced Signal Integrity

Compatible Switch with Optimized

support, which is offered by HDMI

standards and TMDS signal processing. The

/DVI channel also has slower speed, side

Bandwidth of 2.5 Gbps provides 36-

compliance in regards to jitter
