In accordance with the USB standard and to ensure the interoperability of USB devices, Keysight offers:

  • UXR real-time oscilloscope, providing accuracy in waveform representation across a wide frequency range
  • Highly integrated Bit Error Ratio Testers (BERTs), which identify errors introduced into the system when data is received – a critical capability in physical layer characterization, validation, and compliance testing
  • Vector Network Analyzers, which measure the amplitude and phase responses caused by a device, where the resulting transmission and reflection measurements, impedance, and s-parameters are then used for compliance tests and characterization

John Koeter, Senior Vice President of Marketing and Strategy for the Solutions Group at Synopsys, said: “USB4 is the ubiquitous standard for secure, seamless connectivity of high-definition displays and high-throughput peripherals requiring speeds of up to 80Gbps. Synopsys USB controller, PHY and verification IP solutions leverage Keysight’s design and validation technologies to ensure robustness and compliance of the IP at maximum speeds, enabling designers to quickly deliver interoperable products with less risk.”

The next USB4 spec hits 80 Gbps 

The USB Implementers Forum (USB-IF) published the USB4 Version 2.0 specification, a major update to enable USB 80 Gbps performance over the USB Type-C cable and connector. This doubles the maximum aggregate bandwidth of USB to the benefit of higher-performance displays, storage, and USB-based hubs and docks. The USB Type-C and USB Power Delivery (USB PD) specifications have also been updated to support this higher level of data performance.Highlights:Up...

The next USB4 spec hits 80 Gbps

The USB Implementers Forum (USB-IF) published the USB4 Version 2.0 specification, a major update to enable USB 80 Gbps performance over the USB Type-C cable and connector. 

This doubles the maximum aggregate bandwidth of USB to the benefit of higher-performance displays, storage, and USB-based hubs and docks. 

The USB Type-C and USB Power Delivery (USB PD) specifications have also been updated to support this higher level of data performance.

Highlights:

  • Up to 80Gbps operation, utilizing a new physical layer architecture based on PAM3 signal encoding, over existing 40Gbps USB Type-C passive cables and newly defined 80Gbps USB Type-C active cables.
  • Optionally for certain applications, such as driving very-high performance USB4-based displays, the USB Type-C signal interface can be configured asymmetrically to deliver up to 120Gbps in one direction while retaining 40Gbps in the other direction.
  • Updates to data and display protocols to better use the increase in available bandwidth
  • USB data architecture updates now enable Enhanced SuperSpeed USB data tunneling to exceed 20Gbps.
  • Aligns with DisplayPort Revision 2.1 and PCI Express Revision 4.
  • Backward compatibility with all previous versions of USB.

“For engineers, USB4 is defined by its multi-protocol tunneling that architecturally differentiates it from its predecessors – USB 3.2 and USB 2.0,” said Brad Saunders, USB-IF Board Chair and CEO. “This updated technical specification extends USB4 speed and data protocol performance, enabling manufacturers to develop products that can deliver USB 80Gbps in addition to existing USB 40Gbps and USB 20Gbps to end users.”

USB4 delivers 40Gbps bi-directionally

The new USB4 spec was officially published by the USB Implementers Forum (USB-IF).

The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols. It also maintains compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected.

Key characteristics of the USB4 solution include:

  • Two-lane operation using existing USB Type-C cables and up to 40Gbps operation over 40Gbps certified cables
  • Multiple data and display protocols that efficiently share the maximum aggregate bandwidth
  • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3

Over 50 companies are actively participating in the final stages of review of the draft specification.

USB4 promises 40G over new cables

A new USB4 specification under final review promises to be a significant update to the existing USB 3.2 and USB 2.0 architectures.

USB4 is based on the Thunderbolt protocol specification recently contributed by Intel.

Key characteristics 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 total available bandwidth over the bus
  • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3

Over 50 companies are actively participating in the final stages of review of the draft specification. Publication of the final spec is expected around the middle of 2019.

“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said Brad Saunders, USB Promoter Group Chairman. “The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance.”

New Spec for Audio over USB Type-C

The USB Implementers Forum (USB-IF) announced a new USB Audio Device Class 3.0 specification to establish USB Audio over USB Type-C as the primary solution for all digital audio applications, including headsets, mobile devices, docking stations, gaming set-ups and VR solutions.

“USB is the simplest and most pervasive connector available today, making USB Type-C the logical choice for the future of digital audio,” said Jeff Ravencraft, USB-IF President and COO. “We encourage companies interested in adopting USB specifications to take advantage of USB-IF resources to reduce time-to-market and deliver reliable USB products.”

The USB Audio Device Class 3.0 specification makes it easier to support digital audio over USB, add capabilities to reduce power consumption and add support for new features such as hotword detection. It defines minimum interoperability requirements across analog and digital solutions to minimize user confusion when not all hosts or devices support audio consistently. USB Audio over USB Type-C™ allows OEMs to remove the 3.5mm analog audio jack, shaving up to a millimeter off product designs and reducing the number of connectors on a device. Fewer connectors will open the door for innovation in countless ways and make it easier to design waterproof or water-resistant devices.

USB Type-C Gets Authentication Protocol

A new USB Type-C Authentication specification defines cryptographic-based authentication for USB Type-C chargers and devices. This will enable systems to confirm the authenticity of a USB device or USB charger at the moment a wired connection is made – before inappropriate power or data can be transferred.

“USB is well-established as the favored choice for connecting and charging devices,” said Brad Saunders, USB 3.0 Promoter Group Chairman. “In support of the growing USB Type-C ecosystem, we anticipated the need for a solution extending the integrity of the USB interface. The new USB Type-C Authentication protocol equips product OEMs with the proper tools to defend against ‘bad’ USB cables, devices and non-compliant USB Chargers.”

Key characteristics of the USB Type-C Authentication solution include:

  • A standard protocol for authenticating certified USB Type-C Chargers, devices, cables and power sources
  • Support for authenticating over either USB data bus or USB Power Delivery communications channels
  • Products that use the authentication protocol retain control over the security policies to be implemented and enforced
  • Relies on 128-bit security for all cryptographic methods
  • Specification references existing internationally-accepted cryptographic methods for certificate format, digital signing, hash and random number generation
