CY2292SXL-998

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SXL-998 is a factory-programmable, three-phase-locked-loop (PLL) general-purpose clock generator manufactured by Cypress Semiconductor. It utilizes EPROM technology for custom frequency configuration and operates in a 16-pin SOIC package. The device supports configurable 3.3 V or 5 V supply voltages. For commercial temperature operation at 3.3 V, the output frequency range extends from 76.923 kHz to 80 MHz. It features low-skew outputs with skew less than 500 ps and includes power management capabilities such as shutdown and suspend modes.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs: System PLL (SPLL), CPU PLL (CPLL), and Utility PLL (UPLL).
• EPROM programmability allowing full customization of output frequencies.
• Four independent configurable clock outputs (CLKA–CLKD) plus CPUCLK and XBUF.
• Smooth slewing capability on the CPUCLK output between 20 MHz and maximum frequency.

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation.
• Synchronous system timing distribution.
• Low-power applications requiring frequency slewing.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific suffix '998' corresponds to the requested custom frequency configuration, as this indicates a factory-programmed unit. Confirm the operating voltage requirement matches the 'L' suffix designation for 3.3 V operation. Ensure the package type aligns with the 'S' designation for 16-pin SOIC. Cross-reference the part number with official Infineon/Cypress documentation to confirm current availability status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2292SXL variant specifically for commercial temperature ranges (0°C to 70°C) and 3.3 V operation. Use the CY2292FXL if field programmability is required instead of factory programming. Consider the CY2292SI/L/I variants if industrial temperature ratings (-40°C to 85°C) are necessary. Verify that the required output frequencies fall within the 76.923 kHz to 80 MHz range for 3.3 V operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 family consists of EPROM-programmable clock generators upwardly compatible with industry standards ICD2023 and ICD2028. The 'S' prefix denotes factory-programmable devices, while 'F' denotes field-programmable options. The 'X' indicates a lead-free package. This component is part of the third-generation CY229x series designed for diverse clock generation needs in modern synchronous systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants with matching temperature and voltage specifications, such as CY2292SXC for 5 V operation. Field-programmable equivalents like CY2292FXL offer identical electrical characteristics but allow user-side reprogramming. Ensure any substitute maintains the 16-pin SOIC footprint and EPROM architecture if custom frequencies are needed.
