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.
