It is designed to support HDMI/DVI television systems that produce superior high-definition image quality. The differential signal from the 2 HDMI ports is multiplexed through the switch to form a single output HDMI channel going to the HDMI receiver, while the deselected output goes to the high-Z (high impedance) state. It is designed for very low cross-talk, low bit-to-bit skew, high channel-tochannel noise isolation, and low I/O capacitance. This switch offers very little high-speed signal attenuation at the outputs, thus preserving the signal integrity necessary to pass stringent interference requirements. STHDMI001A provides the ability to switch a single source output to various display devices or switch video display devices between multiple sources. It reduces the overall BOM costs by eliminating the need for more costly multi input output controllers Applications ■ DVD Players ■ Front projectors ■ LCD TVs and Monitors ■ Notebook PCs ■ PDPs Order Codes Part Number Temperature Range Package Comments STHDMI001A –65°C to +150°C TSSOP48 STHDMI001ATTR January 2006 Rev.2 1/17 www.st.com 17 STHDMI001A Contents 1 Summary Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.1 Functional Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.2 Function Table STHDMI001A . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2 Maximum Rating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 3 DC and AC Parameters . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 4 3.1 Capacitance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 3.2 Power Supply . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Dynamic Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 4.1 Timing Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 5 ESD Performance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 6 Mechanical Data (Body 48L Pitch 0.5mm) . . . . . . . . . . . . . . . . . . . . . . . . . 14 7 Revision History . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 2/17 STHDMI001A 1 Summary Description 1 Summary Description 1.1 Functional Description The STHDMI001A routes physical layer signals for high bandwidth digital video and is compatible with low voltage differential signaling standards like Transition Minimized Differential Signaling (TMDS). The device multiplexes differential outputs from a video source to one of the two corresponding outputs, then to a common display. The low ON resistance (RON) and low I/O capacitance of the STHDMI001A result in a very small propagation delay. The device integrates SPDT-type switches for 3 differential data TMDS channels and 1 differential clock channel. Figure 1. Connections Diagram 3/17 STHDMI001A 1 Summary Description Table 1.
