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
PI3HDMI1210-A 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.
PI3HDMI1210-A was designed specifi cally to meet ATC-'sink'
requirements. Therefore, Pericom recommends locating this switch
at the sink to switch between multiple sources.
