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 PI3HDMI413
is a 12- to 4-Differential Channel Mux/DeMux Switch. The device
multiplexes differential signals to one of three corresponding out-
puts. 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 1.65Gbps provides the reso-
lution required by the next generation HDTV and PC graphics.
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.
