Description
Pericom Semiconductor’s PI3HDMI
TM
series of switch circuits
are targeted for high-resolution video networks that are based
on DVI/HDMI
TM
standards, and TMDS signal processing. The
PI3HDMI1210-A is a 2-to-1 HDMI
TM
Mux/DeMux Switch. The
device multiplexes differential signals to one of two corresponding
HDMI
TM
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/HDMI
TM
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 HDMI
TM
), and one differential channel is
used for Clock for decoding the TMDS signals at the outputs.
PI3HDMI1210-A was designed specifically to meet ATC-'sink'
requirements. Therefore, Pericom recommends locating this switch
at the sink to switch between multiple sources.
