Unleashing New Connectivity Horizons with USB4

It’s a significant leap in the evolution of laptop connectivity: USB4 has finally broken free from the exclusive realms of Apple and Intel laptops, heralding a new era of unparalleled data transfer and connectivity options. This revolutionary technology, introduced in 2019, incorporates the functionalities of Thunderbolt 3, previously an Intel specialty, and propels the data transfer capabilities to staggering heights.

USB4: A Technological Breakthrough

With USB4, the landscape of laptop connectivity is transformed. Laptops can now achieve a maximum throughput of 40Gbps for all device traffic, a substantial jump from the 10Gbps limit of most non-Thunderbolt 3 ports. This means everything from external GPU cabinets, super-fast external drives, to full-featured docks and monitors, previously a luxury of Intel- or Apple-based laptops, are now universally accessible.

Kandou’s Pioneering Role in USB4 Technology: The Matterhorn™ Retimer

At Kandou, we’re at the forefront of this revolution, developing state-of-the-art USB4 retimers and PCIe Retimers.  Designed specifically for USB4, the Matterhorn™ Retimer is a testament to Kandou’s commitment to enhancing and optimizing the USB4 experience for a wide range of devices. Here’s a closer look at how the Matterhorn™ is shaping the future of connectivity:

1. Low Active Power, Low BOM, Low Risk

Kandou understands the importance of efficiency and reliability. The Matterhorn™ Retimer stands out with its low active power consumption in both USB4 and DP-ALT (DisplayPort Alternate Mode) modes. This efficiency is coupled with full compliance to USB 4, USB 3.2, and DisplayPort standards, ensuring a seamless, worry-free integration for manufacturers and users alike.

2. Fully Optimizing USB4

At the heart of Matterhorn™ is the ability to fully optimize USB4 devices. It ensures that every USB4 device can reach its highest potential, achieving the fastest speeds specified by the USB4 standards. This not only enhances current performance but also future-proofs devices for upcoming versions of USB technology.

3. Highly Manoeuvrable Design

Space is a premium in modern electronic devices. The Matterhorn™ addresses this by offering a compact 5×5 mm package, which is up to 50% smaller than competing products. This compact size gives manufacturers more flexibility and space for other components, making it an ideal choice for a wide array of electronic devices.

4. Simplicity in Integration

Ease of integration is crucial. The Matterhorn™ boasts autonomous environment scoping and dynamic correction, eliminating the need for system tuning. This feature enables longer PCB (Printed Circuit Board) traces and ensures that once installed, the retimer operates seamlessly. This simplicity in integration is a significant advantage for device manufacturers, reducing development time and costs.

Practical Implications: From Theory to Reality

Imagine using an external GPU to boost the graphics performance of a compact laptop or connecting to an ultra-fast external SSD for quicker data access. These are not just theoretical possibilities but practical realities with USB4. Here are just some of the possibilities to super charge your laptop:

External Displays: Connect high-resolution monitors, including 4K and even 8K displays, allowing for high-quality video output. This is especially beneficial for graphic designers, video editors, and gamers.

External GPUs (eGPUs): Enhance your laptop’s graphics performance by connecting an external GPU. This is ideal for gaming, 3D rendering, and video editing, particularly for laptops that don’t have high-end internal GPUs.

High-Speed Data Transfer: Connect external hard drives and SSDs that support USB4 to experience ultra-fast data transfer speeds. This is crucial for professionals who need to transfer large files quickly, such as video files, large databases, or extensive software projects.

Docking Stations: Use USB4 docking stations to connect multiple devices through a single port. This can include monitors, keyboards, mice, network connections, and more, creating a versatile and efficient workstation setup.

Charging Devices: USB4 supports Power Delivery (PD), which means you can charge your laptop or other devices (like smartphones and tablets) through the USB4 port. This feature simplifies charging setups and reduces the need for multiple chargers.

Networking: Leverage USB4 for networking purposes by connecting to Ethernet adapters for a more stable and faster internet connection compared to wireless options.

Audio Interfaces and Musical Instruments: Connect audio interfaces, MIDI controllers, and other musical instruments for high-quality audio recording and production. The high bandwidth of USB4 is beneficial for minimizing latency in audio recordings.

VR and AR Headsets: Connect Virtual Reality (VR) and Augmented Reality (AR) headsets for an immersive experience. The high bandwidth and low latency of USB4 are key for a smooth and responsive VR/AR experience.

Professional Video Equipment: Connect professional video equipment like camcorders or high-end webcams for live streaming or video conferencing with superior quality.

The Future is Now: Windows 11 and USB4

The integration of USB4 in Windows 11 laptops further underscores its significance. Microsoft’s requirement for advanced PCIe support in any laptop with a USB4 port ensures compatibility with both Thunderbolt 3 and USB4/Thunderbolt 4 devices. This move promises a more streamlined and powerful user experience, making USB4 a standard feature in the new generation of laptops.

Navigating the USB4 Landscape

However, understanding the USB4 landscape can be challenging. The technology allows for many optional features, catering to devices ranging from low-power to high-performance. For instance, while advanced display support and Thunderbolt are optional in USB4, they are included in devices like the Asus ZenBook 13. Thus, it’s crucial to discern the specific USB4 features implemented in each device.

USB4 is more than just a technical upgrade; it’s a paradigm shift in how we connect and interact with our devices. From enhancing laptop performance to expanding the scope of external device compatibility, USB4 is indeed a gamechanger. At Kandou, we’re excited to be a part of this transformation, enabling faster, more efficient, and versatile connectivity solutions for a world constantly on the move.
