The PI3HDMI412-B is a 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 source components such as DVD, D-VHS, STB, etc. Block Diagram A0 A1 0B1 1B1 0B2 1B2 Pin Configuration V DD A0 GND A1 GND V DD GND A2 GND A3 GND V DD GND NC A4 GND A5 GND V DD GND A6 GND A7 SEL 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 0B1 1B1 GND 0B2 1B2 A2 A3 2B1 3B1 2B2 3B2 GND 2B1 3B1 GND 2B2 3B2 A4 A5 4B1 5B1 4B2 5B2 GND V DD 4B1 5B1 A6 A7 6B1 7B1 6B2 7B2 GND 4B2 5B2 GND 6B1 7B1 SEL GND 6B2 7B2 Note: 1.
