PI3HDMI412FT-B 2:1 Mux/DeMux High Bandwidth HDMI 1.4 Compliant Signal Switch Features Description 4-Differential Channel 2:1 Mux/DeMux Pericom Semiconductors PI3HDMI series of switch circuits TM are targeted for high-resolution video networks that are based HDMI 1.4 compatible TM on DVI/HDMI standards, and TMDS signal processing. High Bandwidth: 2.7GHz -3dB BW e Th PI3HDMI412FT-B is an 8- to 4-Channel Mux/DeMux Supports both AC coupled and DC coupled signals Switch. e Th device multiplexes differential signals to one of two corresponding outputs. e Th switch is bidirectional and offers Switching speed: 4ns little or no attenuation of the high-speed signals at the outputs. Isolation: -40dB 2.0 Gbps It is designed for low bit-to-bit skew and high channel-to-channel Crosstalk: -31dB 2.0 Gbps noise isolation. ESD: Data bits 8kV contact, select bit 2kV HBM e Th high bandwidth provides the resolution required by the next generation HDTV and PC graphics. Three differential channels Low bit-to-bit skew are used for data (video signals for DVI or audio/video signals for Enable/Disable Time: 9ns HDMI), and one differential channel is used for Clock for decod- Bidirectional ing the TMDS signals at the outputs. Packaging (Pb-free & Green): Because of its passive bidirectional feature, this switch can be 42-pin TQFN (ZH42) used either at the video drivers side or at the receiver side. For PC 48-pin BQSOP (B48) graphics applications, the device sits at the drivers side to switch between multiple display units such as 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 Description Block Diagram 42-pin TQFN 48-pin BQSOP 1 48 V V DD SS 2 47 V V SS DD +A 3 46 D0 D + D +A V 0 SS 0 42 41 40 39 -A 4 45 D0 D0+A VSS 1 38 V D - D -A DD 0 0 +A 44 D1 D0-A 5 2 37 V D + D +A VDD SS 1 1 -A D1 6 43 D1+A D0+ D0+ 3 36 D -A D - 1 1 7 42 V D0- SS 4 35 D1-A D0- D +A D + 2 2 +A 8 41 D2 V D2+A SS 5 34 VSS D - D -A 2 2 -A 9 40 D2 D1+ 33 D2-A D1+ 6 D + D +A +A 3 3 10 39 D3 D1- D3+A 7 32 D1- -A D - D -A 11 38 D3 3 3 V SS 31 D3-A VDD 8 37 V 12 SS V D +B DD VDD 0 9 30 SEL V SS V 13 36 DD SEL D -B D0+B 0 VSS 10 29 +B 14 35 D0 V SS D +B D0-B 1 11 28 D2+ -B 15 34 D0 D2+ D -B D1+B 1 D2- 12 27 +B 16 33 D1 D2- 13 26 D1-B D +B VSS -B 2 17 32 D1 V SS D2+B 14 25 D3+ D -B 31 V 2 18 SS D3+ 24 D2-B D3- 15 +B 30 D2 19 D3- D +B 3 D3+B 16 23 VDD -B 20 29 D2 V SS D -B 3 22 D3-B VSS 17 +B 21 28 D3 V DD 18 19 20 21 -B 22 27 D3 V SS SEL 23 26 V SS V DD 24 25 V DD V SS PS8905A 12/10/12 13-0006 1 V V DD DD VSS VSS V DD V DD VSS VSSPI3HDMI412FT-B 2:1 Mux/DeMux High BW HDMI 1.4 Compliant Signal Switch Pin Description Pin (BQSOP) Pin (TQFN) Pin Name Description 2, 4, 12, 21, 23, 25, 36, 48 2, 8, 16, 18, 20, 30, 40, 42 V + Power supply DD 1, 3, 5, 8, 11, 14, 17, 20, 22, 1, 5, 10, 13, 17, 19, 21, 39, V - Power supply SS 24, 26, 31, 37, 42, 47 41 13 9 SEL Select pin, see truth table 6, 7, 9, 10, 15, 16, 18, 19, 27- 3, 4, 6, 7, 11, 12, 14, 15, 22- +/-x +/-x Dx + CLK Data + Clk bits for TMDS signal 30, 32-35, 38-41, 43-36 29, 31-38 (1) Truth Table Function SEL A Dx to Dx L B Dx to Dx H Note: 1. x=0,1,2,3 Maximum Ratings (Above which useful life may be impaired.
