CY2292SL-1G7

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SL-1G7 is a factory-programmable, three-phase-locked-loop (PLL) general-purpose clock generator manufactured by Cypress Semiconductor. It utilizes EPROM technology for frequency customization and operates within a commercial temperature range of 0°C to 70°C. The device supports configurable 3.3 V or 5.0 V supply voltages. It accepts an external reference crystal between 10 MHz and 25 MHz or an external reference clock from 1 MHz to 30 MHz. Output frequencies reach up to 80 MHz at 3.3 V and 100 MHz at 5.0 V. The component provides four configurable outputs (CLKA–CLKD), a CPU frequency clock, and a buffered reference output in a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs: System PLL (SPLL), CPU PLL (CPLL), and Utility PLL (UPLL).
• EPROM programmability allowing custom frequency generation from a single external source.
• Smooth slewing capability on the CPUCLK output between 20 MHz and maximum frequency limits.
• Power management features including shutdown mode with current draw below 50 µA.

Clock Generators, PLLs, Frequency Synthesizers Applications

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific suffix '1G7' corresponds to the requested factory-programmed frequency configuration. Factory-programmed parts require submission of custom requests via CyClocks software to a local sales representative. Confirm the operating voltage requirement (3.3 V vs 5.0 V) matches the SL suffix designation before ordering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for designs requiring up to three distinct custom frequencies derived from one reference. Ensure the application falls within the commercial temperature range (0°C to 70°C). For field-programmable requirements, consider the CY2292F series instead. Verify that the required output frequencies do not exceed the 80 MHz limit at 3.3 V operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY2292 family of third-generation clock generators. It is upwardly compatible with industry standards ICD2023 and ICD2028. The device is currently offered as part of the Infineon Technologies product portfolio following the acquisition of Cypress Semiconductor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants such as CY2292SC or CY2292SI depending on temperature and voltage needs. Field-programmable equivalents are available in the CY2292FXC or CY2292FXI series. Cross-model substitution requires reprogramming or factory configuration services.
