IEC Formally Adopts USB Type-C, USB Power Delivery and USB 3.1 Specifications

The International Electrotechnical Commission (IEC) along with USB Implementers Forum (USB-IF) announces the formal adoption of USB-IF specifications for high-speed data delivery and enhanced usages for device charging. The development and implementation of these new specifications will help to reduce e-waste and improve re-usability of the power supply.

USB is arguably the most prolific technology worldwide considering the widespread adoption of devices and global consumer recognition. USB Type-C, combined with USB Power Delivery for faster charging and USB performance, is the last cable anyone will ever need. USB-IF is pleased the partnership with IEC has resulted in the approval of these key specifications.

Jeff Ravencraft, President and COO, USB-IF

The new USB-IF specifications will be included in the IEC 62680 Series, Universal Serial Bus interfaces for data and power. USB Type-C specification, IEC 62680-1-3, defines the physical design requirements for the cable and connector. IEC 62680-1-2 provides details that USB Power Delivery (USB PD) should accommodate power levels up to 100W and provide bi-directional power capabilities. Finally,as defined in IEC 62680-3-1, USB 3.1 should enable speeds of up to 10 Gbps for various devices.

VSWR and its Effects on Power Amplifiers

Voltage Standing Wave Ratio results from an impedance mismatch between a source (an amplifier) and a load (test application). This mismatch can influence the performance of the source.

The adoption of these standards will serve to reduce the number of poorly designed, non-compliant aftermarket substitutes from reaching the marketplace and risking consumer safety.
