Cypress Introduces Industrial Temperature Grade Zero Delay Buffers; Aimed at Applications such as Cable Modems and Base Stations.

SAN JOSE, Calif.--(BUSINESS WIRE)--Aug. 27, 1999--

Cypress Semiconductor Corp. (NYSE:CY) today introduced a family of industrial temperature grade zero delay buffers.

Zero delay buffers replicate one timing signal into multiple copies with almost no delay and with low skew between the outputs. Consequently, they are an important ingredient for large, synchronous systems that are used to enable Internet access. Base stations and cable modems are examples of systems that require the reliable distribution of high-speed timing signals and are subject to extreme temperatures. The new devices operate at temperatures from -40 to +80 degrees Centigrade.

"These new products complement many of Cypress's offerings for the data communication and telecommunication markets," said Ian Chen, marketing director of Cypress's Timing Technology Division. "Cypress is responding to strong demand for industrial temperature grade timing products from customers designing communications equipment. In only one week of taking orders, we have already booked over 30 thousand units."

By adding industrial temperature devices to its zero delay buffer family, Cypress expands what was already the industry's widest selection. Cypress's original zero delay buffers set the industry standard, offering support for complex systems, such as switching equipment and servers, that require a great deal of synchronous activity. The recently introduced Spread Aware(TM) product line enables designers of peripherals and consumer products to easily adopt spread spectrum timing technology (as found in Cypress's PREMIS(TM) product line) for reducing EMI emissions.
