Description
Pericom Semiconductor’s PI3HDMI301 3:1 active switch circuit
is targeted for high-resolution video networks that are based
on DVI/HDMI™ standards and TMDS signal processing. The
PI3HDMI301 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 controllable output swings, as well as 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/HDMIBandwidth of 2.5 Gbps provides 36-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 PI3HDMI301 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 passing results for HDMI jitter tests for
all cable lengths: 1meter to 20meters with DeepColor support up
to 36bits.
Pericom also offers the ability to 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 25meter cable length.
