The Latest USB Specifications
The USB-IF released in 2019 the newest USB4™ Specification, which is now available for download on the USB-IF official website. Here are some highlights of USB4™:
- Two-lane operation using existing USB Type-C® cables and up to 40 Gbps operation over 40 Gbps certified cables.
- Multiple data and display protocols to efficiently share the maximum aggregate bandwidth.
- Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3.
USB Power Delivery (USB PD) is a specification which aims to power electronic devices through a single USB cable. USB PD also shortens charging time and helps create more device mobility for the user.
- On May 26, 2021, the USB-IF announced the USB Power Delivery Specification Revision 3.1. This update includes 3 new fixed voltages 28V, 36V, and 48V, which in turn allows power to reach 140W, 180W, and 240W respectively.
More complex than its predecessors, USB Type-C® supports USB 3.1 high-speed transmission and power supply rate of up to 100W, and can be plugged in both positive and negative orientations. Regarding power delivery, USB-C alone can deliver 15W (5V/3A), but with USB PD, it can deliver up to 240W.
- On May 5, 2021, the USB-IF released the USB Type-C® Cable and Connector Specification Revision 2.1. The biggest change from the 2.0 version is the addition of the Extended Power Range (EPR) Cable electrical and identification requirements.
USB Signal Integrity (SI) Test
Continually rising USB transmission rates brings challenges to circuit design. Signal integrity issues become more prominent and it is ever more vital to conduct testing to discover and improve signal issues.
Allion can help you figure out potential risks using professional test equipment, such as oscilloscopes, network analyzers, and various test tools and equipment developed by Allion. By doing so, you catch risks within your products early on and avoid the mess of debugging after the product launch.
Interoperability tests ensure that your USB product can perform the best it can in various environments. Allion has a collection of USB related products and accessories from all over the world, ranging from adapters and power modules to flash memory drives, hubs, and card readers. Allion customizes tests for you to show that your products are seamlessly integrated into the lives of end users.
USB Fixtures and Test Equipment
Customized Fixture Design and Production
As a long-term USB Authorized Test Lab, Allion not only participated in the creation of the USB4 specification but also developed over 100 high-frequency and automated test fixtures. Allion fixtures increase both test accuracy and test speed, making the validation process quick and easy.
Automated Test Equipment
Specifically for USB 3.2 and USB4 cables and connectors, Allion developed the Allion Cable-Connector Multiport System (ACMS), which can be used with a network analyzer and Get_iPar (Intel) for high frequency automated tests.
Aside from certification testing, Allion also provides debugging services, compatibility and interoperability tests, and other USB consulting services.
