Chipidea's New USB PHY Architecture for Offers Industry's Lowest Power Consumption for SoC Designers

Chipidea, a provider of analog/mixed-signal subsystems and intellectual property (IP), has introduced a new generation USB physical layer architecture using 1.8V IO devices that offers the industry's lowest power consumption for System-on-Chip (SoC) designs in the 65nm and 45nm advanced technology nodes.

The new Chipidea architecture is the latest from the industry's most complete line of USB IP offerings and provides a power consumption of around 70mW. The usage of 1.8V IO devices is an industry first and extends Chipidea's USB catalog from IO devices of 3.3V and 2.5V to offer designers the widest range of options for their USB connectivity integration strategies.

Fully compliant with the USB 2.0 specification, Chipidea's 1.8V USB PHY guarantees D+ and D- protection to withstand transient short-circuit voltage without damage. The core also features analog programmability for fine-tuning, allowing designers to achieve the best performance for their integrated systems. The IP is available as a standalone PHY or matched with a USB controller.

"We are offering a new generation of USB IP cores using 1.8V devices for designers that require the lowest power consumption," said Celio Albuquerque, division director of Chipidea's Physical Solutions Division. "This 1.8V platform extends our portfolio to a new IO device choice, while maintaining the advantages of our IP, including analog programmability, built-in self-test (BIST) and full USB2.0 compliance."

Chipidea's wide selection of certified USB cores is available at several of the industry's leading foundries and advanced process nodes. The IPs have been certified to provide the industry's greatest degree of design flexibility in the 0.18µm, 0.13µm, 90nm and 65nm process nodes. The company's 1.8V USB PHY architecture is the latest addition to a line of wired interface IP that enjoyed revenue growth of 105 percent in 2005, far outpacing all other USB IP providers, according to market researcher Gartner Dataquest.
