IP group develops integrated USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 3.0 PHY and controller solution(C)1995-2009 M2 COMMUNICATIONS LTD LTD 1 Laron-type dwarfism 2 Leukotriene D 3 Long-term depression, see there 4. Long-term disability http://www.m2.com Gennum Corporation (TSX:GND), a designer of semiconductor solutions and intellectual property (IP) cores, announced on Monday (9 March) that its Snowbush IP group has developed the industry's first available integrated USB 3.0 SuperSpeed PHY and controller solution. SuperSpeed USB, published by the USB Implementers Forum The USB Implementers Forum, USB-IF, is a non-profit organisation to promote and support the Universal Serial Bus. Its main activities are the promotion and marketing of USB, Wireless USB, USB On-The-Go, and the maintenance of the specifications, as well as a compliance program. , is the latest version of a standard interface specification. The standard, also called USB 3.0, defines an interface that operates in full-duplex mode, enabling the host and device to download and receive data simultaneously. The two-way communication, combined with a more than tenfold increase in data-transfer rate to 5Gb/s in each direction, enables performance improvements over the previous USB 2.0 standard which supported 480Mb/s and half-duplex (one-way) communication. SuperSpeed USB devices are expected to be capable of downloading and uploading much larger files to a computer in a fraction of the time it currently takes. According to the company, the integrated Snowbush device PHY and controller solution satisfies the 5Gb/s speed requirement of USB 3.0 and exceeds the specifications for jitter and jitter tolerance, providing margin to designers for creating robust products with high interoperability. The solution also satisfies the low-power requirements of the standard, supporting all SuperSpeed power modes and offering programmability of the driver and receiver to help reduce power consumption. The new IP block employs a range of techniques to ensure high performance, reduced jitter and increased noise immunity, including: a dual-loop hybrid clock-and-data recovery (CDR (1) See CD-R and extension. (2) (Call Detail Reporting) See call accounting. (3) (Common Data Rate) A standard sampling rate for digital video for 480i and 576i systems. The rate is 13.5 MHz. See ITU-R BT. ) architecture which recovers the clock with less jitter; a coupled ring oscillator VCO design; internal voltage and current regulation for sensitive circuits; fully differential circuitry and clock signaling; as well as extensive use of guard rings within the macro, the company said. The Snowbush integrated PHY and controller IP is available immediately for licensing and can be provided for manufacture in 90nm, 65nm and 45nm processes. No pricing details were disclosed.
