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