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.
