Description
Pericom Semiconductor’s PI3HDMITM series of switch circuits
are targeted for high-resolution video networks that are based on
DVI/HDMITM standards, and TMDS signal processing. The PI-
3HDMI1210 is a 2-to-1 HDMITM Mux/DeMux Switch. The device
multiplexes differential signals to one of two corresponding HDMITM
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/HDMITM data rate of 4.0Gbps 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 HDMITM), 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.
