There might be a lot of hype about USB 3.0 these days, but the USB 3 standard was actually released in 2008. Wa_cq_url: "/content/Why All the Hype About USB 3 ? Wa_audience: "emtaudience:business/btssbusinesstechnologysolutionspecialist/architect/hardwareengineer", Wa_english_title: "Universal Serial Bus 3.0 and 2.0 Specifications", Wa_rdcproducts: "rdcproducts:ioproducts", Wa_upeproducts: "upeproducts:ioproducts", Wa_emtcontenttype: "emtcontenttype:donotuse/webpage/article", Peripheral and IP vendors will be able to develop their designs, insulated from the high-speed, and analog circuitry issues associated with the USB 2.0 interface, thus minimizing the time and risk of their development cycles. ASIC vendors and foundries will implement the UTM and add it to their device libraries. This document defines an interface to which ASIC and peripheral vendors can develop. The intent of the UTMI is to accelerate USB 2.0 High-speed, Full-speed, and Low-speed peripheral development. The UTMI specification covers the physical interface and many operational aspects of the USB 2.0 Transceiver Macrocell (UTM). USB 2.0 Transceiver Macrocell Interface (UTMI) › It does not evaluate the functionality of the USB companion controllers. The EHCI compliance testing program measures an EHCI controller implementation for conformance to the EHCI specification and evaluates the functionality of the EHCI controller function of a USB 2.0 host controller. These specifications address the need for portable devices to communicate with each other and with USB peripherals when a PC is not available.Įnhanced Host Controller Interface (EHCI) Compliance Testing Program › On-the-go Supplement to the USB 2.0 Specification › USB 2.0 Specification › (download from the USB-IF website): Technical details necessary to understand USB 2.0 requirements and to design USB 2.0-compatible products. ![]()
