San Jose, Calif. Cypress Semiconductor Corp. has introduced a clock generator specifically developed to provide the high performance clock signals required for both the Rambus Inc. XDR (Extreme Data Rate) memory systems and the FlexIO processor bus interface supporting applications that employ the Cell processor architecture.

Cypress' announcement comes on the heels of Rambus' release of its mass production specification for the XDR Clock Generator (XCG), which supports high-volume production infrastructure for XDR memory products.

Cypress' XCG dubbed the CY24271ZXC provides four programmable differential outputs using a reference input clock of either 100 MHz or 133 MHz to enable the 6.4 GB/sec XDR memory system and the up to 8.0 GHz FlexIO processor bus. The XCG also supports spread spectrum modulation, reducing the EMI generated from the clock distribution network.
The CY24271ZXC XCG features 25-picosecond typical cycle-to-cycle jitter; -135 dBc/Hz typical phase noise at 20-MHz offset; 300 to 800 MHz high-speed clock support; and quad (open drain) differential output drivers. It supports frequency multipliers, including 3, 4, 5, 6, 8, 9/2, 15/2 and 15/4, and 2.5-V operation.
The CY24271ZXC XCG is available today in a 28-pin TSSOP package. Pricing for the device is less than $2.50 each in 1000-unit quantities.
