SAN JOSE, Calif. National Semiconductor Corp. said that it is acquiring Xignal Technologies AG, a German-based developer of high-speed data converters.
Xignal is a developer of continuous-time sigma delta analog-to-digital converters (ADCs), a technology that enables high- resolution (12-bits and above) ADCs at megahertz (MHz) speeds with reduced power levels compared to traditional pipeline solutions.
The continuous time architecture, according to National (Santa Clara, Calif.), greatly simplifies system design as it allows incorporation of other signal path functions, such as on-board clocks, low- noise amplifiers and external filters.
The acquisition of Xignal's technology and design team strengthens National's growing position in the data conversion market. This investment in continuous-time sigma delta intellectual property (IP) augments
National's existing sigma delta IP and complements its ongoing sigma delta technology development. Initial products from the acquisition will be targeted at applications requiring a high level of signal path integration and extremely low power, such as medical ultrasound imaging, and will expand over time to address test and measurement and communication applications.
