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
PI3HDMI412FT is an 8- to 4-Channel Mux/DeMux Switch. The
device multiplexes differential signals to one of two corresponding
outputs. The switch is bidirectional and offers little or no attenua-
tion 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 1.65Gbps provides the
resolution 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.
