PI3HDMI412FT 4-Differential Channel, 2:1 Mux/DeMux, DVI/HDMI Compliant Signal Switch with Flow-through Pin Out Description Features 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 PI3HDMI412FT is an 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. 4-Differential Channel 2:1 Mux/DeMux DVI, HDMI rev 1.1, and HDMI rev 1.2 signal compatible -3dB BW = 1.5 GHz (3.0Gbps) Crosstalk: [email protected] Switching speed: 4ns Isolation: [email protected] ESD: Data bits @ 8kV HBM, select bit @ 2kV HBM Near-Zero Prop Delay: 200ps max. Low bit-to-bit skew Hot insertion capable Enable/Disable Time: 9ns Bidirectional Packaging (Pb-free & Green): - 42-pin TQFN (ZH42) - 48-pin BQSOP (B48) 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 Description Block Diagram 42-pin TQFN ���� ���� ���� ���� ���� ���� � �� � �� � �� � �� � �� � �� � �� ���� ���� � �� ���� ���� ���� ���� ���� ���� ���� ���� � � � � � � � � � �� �� �� �� �� �� �� �� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� ��� �� �� �� �� ��� �� �� �� �� ��� ��� ��� ��� ��� 06-0200 48-pin BQSOP ��� ��� ��� ��� • • • • • • • • • • • • • 1 �� �� �� �� �� �� �� �� �� �� �� �� �� �� �� �� �� ���� ���� ���� ���� ���� ���� ���� ���� ��� ���� ���� ���� ���� ���� ���� ���� ���� VSS VDD VSS VDD VSS D0+ D0VSS D1+ D1VSS VDD SEL VSS D2+ D2VSS D3+ D3VSS VDD VSS VDD VSS 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 PS8798A VDD VSS D0+A D0-A D1+A D1-A VSS D2+A D2-A D3+A D3-A VSS VDD D0+B D0-B D1+B D1-B VSS D2+B D2-B D3+B D3-B VSS VDD 08/08/06 PI3HDMI412FT 4-Differential Channel, 2:1 Mux/DeMux, DVI/HDMI Compliant Signal Switch with Flow-through Pin Out Pin Description Pin # (BQSOP) Pin # (TQFN) Pin Name(1,2) 2, 4, 12, 21, 23, 25, 36, 48 2, 8, 16, 18, 20, 30, 40, 42 VDD + Power supply 3.30 1, 3, 5, 8, 11, 14, 17, 20, 22, 24, 26, 31, 37, 42, 47 1, 5, 10, 13, 17, 19, 21, 39, 41 VSS - Power supply 13 9 SEL Select pin, see truth table 6, 7, 9, 10, 15, 16, 18, 19, 2730, 32-35, 38-41, 43-46 3, 4, 6, 7, 11, 12, 14, 15, 22-29, 31-38, Dx+/-n Notes: 1. x = 0,1,2,3 2. n = A or B Truth Table(1) Data + Clk bits for TMDS signal Maximum Ratings Function SEL Dx to DxA L DxB H Dx to Description (Above which useful life may be impaired.
