PI3HDMI412FT
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 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 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 sources components such as DVD, D-VHS, STB, etc.
