Silego Technology Introduces the GreenCLK Product Family: the World's First High Accuracy Microwatt 32.768 kHz Clock Generator on Standard Silicon.

GreenCLKs Are Used to Integrate the 32.768 kHz Tuning-Fork Crystal Function into Standard CMOS Silicon at Comparable Power and Increased Accuracy Over Temperature

SANTA CLARA, Calif. -- Silego Technology, Inc. announces a family of GreenCLK 32.768 kHz generating clock ICs. Most electronic systems today contain a low frequency and ultra-low power 32.768 kHz crystal for time keeping, system wake up, or clocking an ultra-low power microcontroller. Most electronic systems also contain a high frequency and performance MHz AT Cut crystal for serial data communication, processors, RF transceivers, and high speed memory interface.

The GreenCLK products are targeted at portable media players, camcorders, LCD and Plasma TVs, smart phones, notebook, netbook, and desktop PCs, or almost anywhere a 32.768 kHz tuning fork crystal and a MHz crystal are found together in a system. GreenCLK products come in a variety of packages: 2x2 mm TDFN or 3x3 mm TQFN with multiple 32.768 kHz and MHz outputs.

The GreenCLK products contain the first 32.768 kHz silicon technology that is competitive with quartz in terms of size, power consumption, and frequency accuracy. In fact, the over temperature accuracy from -40 to 85C is improved by more than 5x compared to a typical tuning fork crystal. During system sleep mode, GreenCLK consumes less than 2.5 uA while generating the 32.768 kHz clock.

"Silego's GreenCLK products offer designers an alternative to tuning-fork 32.768 kHz quartz with reduce component count, more mechanical robustness, and better performance over temperature," said John McDonald, Vice President of Marketing and Sales at Silego. "The success of the GreenCLK family supports Silego's corporate goal of providing ICs that reduce component count, and simplify design, while saving power and board space."

The GreenCLK products contain a variety of features depending on part number, including 4.2V support for direct connection to Li-Pol batteries, ML coin cell battery chargers, automatic power switching between battery backup and active power modes, and various output level controls from less than 1V to 3.3V.

Prices and Availability

GreenCLK products are in volume production. Samples, datasheets, demonstration boards and product selection chart are available from the Silego Website GreenCLK products are priced competitively depending on configured feature set. Contact Silego for high volume pricing. GreenCLK products are more competitive than 32.768 kHz quartz-based solutions.
