PI3HDMI1212
High-performance HDMI 1.1 and 1.2 Compatible Signal Switch w/
Integrated Side-band Signal Support
Description
Features
Pericom Semiconductor’s PI3HDMI series of switch circuits are
targeted for high-resolution video networks that are based on DVI/
HDMIstandards,andTMDSsignalprocessing.ThePI3HDMI1212
is a 2-to-1 HDMI Mux/DeMux Switch. The device multiplexes
differential signals to one of two corresponding HDMI 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.
• 4-Differential Channel 2:1 Mux/DeMux + 4-Channel 2:1
Mux/DeMux
• DVI, HDMI 1.1, 1.2 and 1.3 signal compatible
• Data Rate: 4.0Gbps for high speed channels
• Supports both AC coupled and DC coupled signals
• Switching speed: 4ns
• Isolation: -40dB@1GHz for high-speed channels
• Integrated ESD protection
ThemaximumDVI/HDMIdatarateof4.0Gbpsprovidestheresolu-
tion required by the next generation HDTVand PC graphics. Three
differential channels are used for data (video signals for DVI or
audio/videosignalsforHDMI), andonedifferentialchannelisused
for Clock for decoding the TMDS signals at the outputs.
• High-speed data bits: 12kV HBM
8kV contact
• Side band signal bits: 2kV HBM
• Low bit-to-bit skew
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.
• Enable/Disable time: 9ns
• Bidirectional
• Packaging (Pb-free & Green):
