San Jose, Calif.--March 16, 1998--Cypress Semiconductor (San Jose) introduced a line of 100-MHz CY228x clock generators and CY231xNZ SDRAM buffers for next-generation PC designs.
The new family of products allows PC designers to take advantageof the shift from 66 MHz to higher performance 100-MHz system busfrequencies. The clock products are usable with the latest generationof core logic chipsets and support processors in Slot and Socketpackages.
The CY228x and CY231xNZ are designed for low EMI and offer anumber of options to allow designers maximum flexibility inimplementing their systems. The CY228x family includes 48-pinall-in-one motherboard solutions, as well as compact 28-pin solutions,all of which can be used with separate CY321xNZ SDRAM buffer chips.
The two-chip solution allows designers to minimize system noiseby placing the buffer chip closer to the SDRAM modules, thuseliminating long 100-MHz traces on the motherboard. The CY228x devicesare also available with Cypress's proprietary spread spectrumtechnology, a new technique that involves controlled spreading of theoutput frequencies to reduce overall system EMI.
The CY228x devices provide all the outputs necessary to controlsystem, bus, and peripheral components in server, workstation, desktop,and mobile PCs. The CY2280, CY2281, and CY2282 are optimized forPentium II designs, whereas the CY2283 and CY2284 are targeted toward Socket 7 designs using chipsets from Acer Labs and VIA Technologies.
The CY231xNZ can be used as SDRAM buffer companions to any of theCY228x family and provide support for up to 4 SDRAM DIMMs or up to 6SO-DIMMs.
The CY228x and CY231x devices are available now. Pricing for theCY228x family starts at $3.15 in 10,000-unit quantities, and theCY231x family starts at $2.75, also in 10,000-unit volumes.
