TMDS341APFC

Specialized Overview

The TMDS341APFC is a 3-to-1 DVI/HDMI switch IC designed to route up to three digital video sources to a single display terminal. It supports four TMDS channels per port along with hot-plug detection and control signals. The device operates at a supply voltage of 3.3 V, featuring a maximum on-resistance of 50 ohms and propagation delays of 2 ns. It is housed in an 80-pin TQFP package (12x12 mm) and functions within a temperature range of 0°C to +70°C.

Specialized Feature Summary

• Supports switching between three DVI or HDMI input ports to one output
• Handles four TMDS data channels plus control signals per port
• Integrates hot-plug detection circuitry for automatic source management

Specialized Applications

• Digital signage systems requiring multi-source selection
• Home theater PCs connecting multiple media players
• Professional AV equipment routing video feeds
• Industrial displays with redundant input options

Specialized Procurement Notes

Verify the specific suffix (e.g., PFC vs. PFCR) against the manufacturer datasheet to confirm packaging type such as tray or reel. Ensure the operating temperature range meets environmental requirements. Confirm pin compatibility for the 80-TQFP footprint during PCB layout validation.

Specialized Selection Notes

Select this component when a single display requires access to three distinct DVI or HDMI sources. It is suitable for applications needing low signal distortion and fast switching speeds. Consider thermal dissipation capabilities given the power rating and package size for enclosed designs.

Specialized Part Context

This part belongs to Texas Instruments' family of video interface switches. It complements other TMDS controllers by providing physical layer routing for digital video standards. The device simplifies system architecture by eliminating external multiplexing components for standard consumer and professional video interfaces.

Specialized Replacement Considerations

Check for direct substitutes like the TMDS341 without suffix variations if packaging differs. Verify electrical parameters match for equivalent performance in existing designs.

Specialized FAQ

Does the TMDS341APFC support HDCP?

The device acts as a passive switch for TMDS signals and does not process HDCP encryption or decryption itself.

What is the maximum number of TMDS channels supported?

Each input port supports four TMDS data channels plus auxiliary control lines.
