Lontium LT8631SX High-Speed 3-Port HDMI/DVI Switch

Shenzhen Mingjiada Electronics Co., Ltd., as a renowned distributor of electronic components, has long supplied the Lontium LT8631SX high-speed three-port HDMI/DVI switch, providing a cost-effective solution for high-definition video transmission.

Based on ClearEdge™ technology and compliant with HDMI 1.4/DVI 1.0 specifications, this switch connects multiple HDMI/DVI source devices to high-definition televisions (HDTVs).

【Core Features of the LT8631SX】

The LT8631SX is a 3-input, 1-output HDMI/DVI link switch. It supports data transfer rates up to 3.4Gbps and features deep colour support, ensuring a high-quality video transmission experience.

The LT8631SX integrates RX-side on-die termination (ODT) and management circuitry, enabling cost-effective system design while significantly enhancing overall performance.

High Compatibility and Flexibility:

The LT8631SX is fully compliant with HDMI 1.4 and DVI 1.0 standards. Its source/sink connection detection capability provides considerable flexibility for system management, while I²C control support facilitates user operation and integration.

Low Cost and Simplified Manufacturing:

The LT8631SX integrates HPD switching, DDC switching, and a +5V power indicator switch, substantially reducing system manufacturing costs and simplifying motherboard routing complexity.

Stable and Reliable Performance:

The LT8631SX operates from a single 3.3V supply and features a 5V-tolerant DDC interface.

ESD protection for HPD, DDC, and data/clock channels meets JESD22-A114-B Class 3A standards, ensuring product stability and reliability.

【LT8631SX Core Technology】

Based on ClearEdge™ technology, the LT8631SX complies with HDMI 1.4/DVI 1.0 specifications and supports data transfer rates up to 3.4Gbps.

This enables the LT8631SX to process high-quality audio-visual signals, even supporting deep colour technology for an enhanced colour experience.

The LT8631SX integrates RX-side on-die termination (ODT) and management circuitry. This design not only enables cost-effective system implementation but also enhances overall performance.

Furthermore, the integrated DDC and HPD switches further reduce system manufacturing costs and simplify board layout.

【LT8631SX Architecture Features】

The LT8631SX operates from a single 3.3V supply with low added jitter, ensuring stable signal transmission.

Its 5V-tolerant DDC interface and Class 3A ESD protection (per JESD22-A114-B) significantly enhance durability and electrostatic immunity.

The LT8631SX supports source/receiver connection detection, enabling flexible system management.

It also supports I²C control for convenient advanced feature configuration.

【LT8631SX Applications】

As a three-to-one (3:1) switch, the LT8631SX is ideally suited for rear panels of HDTVs and A/V receivers.

Consumers can thereby connect multiple HDMI/DVI devices such as high-definition DVD players, set-top boxes, and gaming consoles.

The LT8631SX plays a critical role in front-panel buffers for high-definition televisions (HDTVs), standalone switches, multi-input displays, projectors, and A/V receivers.
