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 TMDS Signaling Data Rate: 1.65Gbps Crosstalk: [email protected] Switching speed: 4ns Isolation: [email protected] ESD: Data bits @ 8kV HBM, select bit @ 2kV 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) 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 � �� � �� � �� � �� � �� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ���� ��� 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 PS8798 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 12/05/05 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 Description 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, 27-30, 32-35, 38-41, 43-46 3, 4, 6, 7, 11, 12, 14, 15, 22-29, 31-38, Dx+/-x + CLK+/-x Data + Clk bits for TMDS signal Truth Table Function SEL N to NA L N to NB H Maximum Ratings (Above which useful life may be impaired.
