Cypress' clock generator

Cypress Semiconductor Corp. has introduced a clock generator that has been developed specifically to provide high-performance clock signals for the Rambus Inc. Extreme Data Rate (XDR) memory systems and the FlexIO processor bus interface that support applications employing the new Cell processor architecture.

The Cell processor, developed jointly by IBM, Sony and Toshiba, is optimized for the kind of real-time calculations needed in today's broadband, media-rich environment such as game consoles, consumer electronics and advanced computing systems. It employs nine processors on a single chip, with a specially designed 300Gbps bus knitting the processors into a single machine. The Rambus XDR memory and FlexIO processor bus interfaces account for 90 percent of the Cell processor signal pins, the company explained, providing an unprecedented aggregate processor I/O bandwidth of approximately 100Gbps.

The Cypress XDR clock generator (XCG) provides four programmable differential outputs using a reference input clock of either 100MHz or 133MHz to enable the 6.4GBps XDR memory system and the up to 8GHz FlexIO processor bus. The XCG also supports spread spectrum modulation, Cypress said, reducing the EMI generated from the clock distribution network.

"The Cypress XCG adds a new capability to our consumer clock portfolio, providing a very high-performance clock generator to meet the needs of next-generation digital entertainment systems," said Mehdi Behnami, product marketing manager of Cypress's General Purpose Clocks Business Unit. "It gives us inroads into high-performance, high-volume applications with major customers worldwide."

"Working with industry leaders such as Cypress to bring advanced clock generators to the market helps to build out the high-volume production infrastructure for our XDR memory solution," said David Nguyen, VP of engineering at Rambus Inc. "The XDR clock generator is a critical component in XDR and FlexIO implementations, providing the high performance clock signals required for advanced high-speed applications."

The CY24271ZXC XCG is available today in a 28-pin TSSOP package. Pricing for the device is under $2.50 in 1,000-unit quantities.
