| COMPANY CONFIDENTIAL PI3HDMI412-A 4-Differential Channel, 2:1 Mux/DeMux, DVI/HDMI Compliant Signal Switch based on TMDS Signaling Standard Features * * * * * * * * * * * * * 4-Differential Channel 2:1 Mux/DeMux TMDS Signaling Data Rate: 1.65Gbps Crosstalk: -25dB@825MHz Switching speed: 4ns Isolation: -30dB@825MHz ESD: Data bits @ 8kV HBM, select bit @ 2 kV HBM Near-Zero Prop Delay: 250ps max. Low bit-to-bit skew Hot insertion capable Enable/Disable Time: 9ns Bidirectional Packaging (Pb-free & Green): - 42-pin TQFN (ZH) - 48-pin BQSOP (B) Description Pericom Semiconductor's PI3HDMI series of switch circuits are targeted for high-resolution video networks that are based on DVI/ HDMI standards, and TMDS signal processing. The PI3HDMI412-A 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 Pin Descriptions (Top View) VSS VDD C1+ C1VSS VDD SEL VSS C2+ C2VDD VSS C3+ C3VSS VSS VDD VSS VSS VDD VSS VSS C0+ C0- 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 VDD VSS C0+A C0-A C1+A C1-A VSS C0+B C0-B C1+B C1-B VSS VDD C2+A C2-A C3+A C3-A VSS C2+B C2-B C3+B C3-B VSS VDD 42-pin TQFN 1 48-pin BQSOP PS8814 02/08/06 COMPANY CONFIDENTIAL PI3HDMI412-A 4-Differential Channel, 2:1 Mux/DeMux, DVI/HDMI Compliant Signal Switch based on TMDS Signaling Standard Pin Description Truth Table Function N to NA N to NB SEL L H Pin # 5, 8, 13, 18, 20, 30, 40, 42 1, 4, 10, 14, 17, 19, 21, 39, 41 9 2, 3, 6, 7, 11, 12, 15, 16, 31-38, 22-29 Pin Name VDD VSS SEL CXtx Description + Power supply 3.30 - Power supply Select pin, see truth table Data + Clk bits for TMDS signal Maximum Ratings (Above which useful life may be impaired.
