Description
Pericom Semiconductor’s PI3HDMI series of switch circuits are
targeted for high-resolution video networks that are based on DVI/
HDMI standards, and TMDS signal processing. The PI3HDMI1212
is a 2-to-1 HDMI Mux/DeMux Switch. The device multiplexes
differential signals to one of two corresponding HDMI inputs. The
switch is bidirectional and offers little or no attenuation of the high-
speed signals at the outputs. It is designed for low bit-to-bit skew
and high channel-to-channel noise isolation.
The maximum DVI/HDMI data rate of 4.0Gbps provides the resolu-
tion required by the next generation HDTV and PC graphics. Three
differential channels are used for data (video signals for DVI or
audio/video signals for HDMI), and one differential channel is used
for Clock for decoding the TMDS signals at the outputs.
Because of its passive bidirectional feature, this switch can be
used either at the video drivers side or at the receiver side. For PC
graphics applications, the device sits at the drivers side to switch
between multiple display units such as PC LCD monitor, projector,
TV, etc. For consumer video applications, the device sits at the
receiver end to switch between the source components such as
DVD, D-VHS, STB, etc.
