| STHDMI001A 3.3V, High Bandwith, 2-to-1 High Definition Multimedia Interface (HDMI) Switch with Single Enable Features Compatible with HDMI v1.1 and DVI v1.0 digital interfaces Data rate per channel for UXGA: 1.65Gbps 165MHz speed operation supports all video formats up to 1080p and SXGA (1280x1024 at 75 Hz) Low RON: 5.5 (typ) VCC operating range: 3.0V to 3.6V Low current consumption: 20A ESD Human Body Model HMB Voltage: - 4KV for HDMI connector inputs - 2KV for all other I/Os Channel ON Capacitance: 6pF (typ) Switching speed: 9ns Near-Zero Propagation Delay: 250ps Low crosstalk: -32dB at 825MHz Bit-to-Bit Skew: 200ps Very Low Ground Bounce in Flow Through Mode Data and control inputs provide an undershoot clamp diode Wide bandwidth minimizes skew and jitter Hot insertion capable Supports bi-directional operation Available in the TSSOP48 package -40C to 85C operating temperature range TSSOP48 Description The STHDMI001A is a differential Single Pole Double Throw (SPDT) 2-to-1, low RON, bidirectional HDMI switch. 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 STHDMI001A January 2006 Temperature Range -65C to +150C Package TSSOP48 Comments STHDMI001ATTR Rev.2 1/17 www.st.com 17 STHDMI001A Contents 1 Summary Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.1 1.2 Functional Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 Function Table STHDMI001A . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 2 3 Maximum Rating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 DC and AC Parameters . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 3.1 3.2 Capacitance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Power Supply . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 4 Dynamic Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 4.1 Timing Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 5 6 7 ESD Performance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 Mechanical Data (Body 48L Pitch 0.5mm) . . . . . . . . . . . . . . . . . . . . . . . . . 14 Revision History . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 2/17 STHDMI001A 1 Summary Description 1 1.1 Summary Description 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.
