IT6636/IT66362: The Professional Grade HDMI2.1 48Gbps Retiming Switch

In the era of 8K Ultra-HD and 4K120 High-Frame-Rate displays, the challenge for system designers has shifted from "simple switching" to "signal preservation." As bandwidth reaches 48Gbps, traditional passive switches and redrivers often fail to maintain link stability over practical distances.
ITE Tech. Inc. presents the IT6636 (3-in-1-out) and IT66362 (2-in-1-out)-not just switches, but high-performance Retimers designed to anchor ProAV systems, advanced docking stations, and high-end commercial displays with uncompromising stability.

Retiming Architecture: Beyond Standard Redrivers

Unlike common Redriver solutions (such as Pericom PI3HDX12211/21) that merely amplify noise along with the signal, the IT6636 series utilizes a Retimer architecture. It cleans jitter and regenerates the clock/data signals at the physical layer.

• Superior Reach: While competitor solutions are often limited to 2-meter traces, the IT6636 supports up to 5 meters for both input and output, offering 2.5x the transmission distance for flexible system layouts.
• Jitter Elimination: Provides a cleaner eye diagram and more robust link training than GSCoolink GSV6703, ensuring seamless handshaking with diverse 8K sources.

High Integration: Minimizing BOM and Design Complexity

The IT6636 series is engineered to be a "Single-Chip Solution," significantly reducing the need for external components compared to Parade PS8431 or other MCU-less alternatives.

• Embedded MCU & Flash: Handles complex HDMI2.1 protocol negotiation internally, drastically reducing the customer's software development effort.
• Massive IO Expansion: Equipped with 10 GPIOs, providing significantly better system control and peripheral expansion capabilities than competing chips.
• Crystal-Free Design: Further minimizes PCB footprint and BOM cost, allowing for sleeker, more compact industrial designs

Thermal Excellence & Power Efficiency

High performance shouldn't come at the cost of high heat. The IT6636/IT66362 is optimized for low-power operation, delivering superior thermal efficiency over high-power alternatives.

• Auto-Power Saving: Intelligently scales power consumption based on signal presence, making it ideal for bus-powered docking stations and slim-bezel monitors.
• Reliability: Lower operating temperatures ensure a longer product lifespan and better performance stability in 24/7 commercial environments.
