CY2292SL-1G8

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SL-1G8 is a factory-programmable, three-phase-locked-loop (PLL) general-purpose clock generator manufactured by Cypress Semiconductor. It operates in a 16-pin SOIC package and supports configurable 3.3 V or 5 V supply voltages. The device generates up to four independent output frequencies from a single external reference source, utilizing an internal EPROM for custom frequency configuration. Key electrical parameters include a maximum output frequency of 80 MHz at 3.3 V operation and 100 MHz at 5 V operation. The input reference range spans 10 MHz to 25 MHz for crystals or 1 MHz to 30 MHz for external clocks.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs (CPU, System, Utility) with EPROM programmability
• Four configurable outputs (CLKA–CLKD) with low skew (<500 ps)
• Smooth CPUCLK slewing between 20 MHz and maximum frequency
• Power management via shutdown and suspend modes

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Synchronous system timing
• Low-power green applications requiring frequency scaling

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '1G8' against official Infineon/Cypress ordering documentation, as standard datasheets list generic suffixes like 'SC', 'SL', 'SXC', 'SXL'. Confirm that the part corresponds to the commercial temperature range and 3.3 V operation specified by the 'L' designation. Ensure compatibility with the 16-pin SOIC package form factor.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when custom frequency synthesis from a single reference is required without field reprogrammability. The 'SL' suffix indicates commercial temperature range (0°C to 70°C) and 3.3 V operation. Verify that the required output frequencies fall within the 76.923 kHz to 80 MHz range for 3.3 V systems. Consider the CY2292F series if field programmability is needed instead.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 family is upwardly compatible with industry-standard ICD2023 and ICD2028 devices. Cypress Semiconductor Corporation has been acquired by Infineon Technologies, which continues to support the product line under the Infineon portfolio while maintaining original part numbers and document continuity.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants such as CY2292SC (5V/Commercial), CY2292SI (5V/Industrial), or CY2292FI (Field Programmable). Cross-family alternatives like the CY2291 (two-PLL version) may be considered if fewer outputs are sufficient.
