CY2292SC-833

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SC-833 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 within a commercial temperature range of 0°C to 70°C. The device supports configurable 5V or 3.3V supply voltages and provides four independent configurable outputs alongside a CPUCLK output with smooth slewing capabilities. Designed for PC motherboard applications, it generates up to three custom frequencies from a single external source while maintaining low skew and jitter characteristics across its outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs (System, CPU, Utility) for flexible clock generation
• EPROM programmability allowing factory customization of output frequencies
• Configurable 5V or 3.3V operation with low-skew, low-jitter outputs
• Smooth slewing on CPUCLK output for power management

Clock Generators, PLLs, Frequency Synthesizers Applications

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific 833 suffix configuration against the datasheet's custom configuration request procedure. Factory-programmed parts require submission of frequency specifications via CyClocks software to a local FAE. Confirm package type availability, as standard CY2292SC parts are typically supplied in 16-pin SOIC packages.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for designs requiring three distinct PLL sources with EPROM-based customization. Ensure the required output frequencies fall within the 76.923 kHz to 100 MHz range for 5V operation or 76.923 kHz to 80 MHz for 3.3V operation. Verify that the input reference frequency matches the supported 10–25 MHz crystal or 1–30 MHz external clock ranges.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292SC-833 belongs to the CY2292 family of three-PLL clock generators. It is upwardly compatible with industry standards ICD2023 and ICD2028. The 'SC' designation indicates a factory-programmable device in a commercial temperature grade (0°C to 70°C) operating at 5V, while the '833' represents a unique factory-defined frequency configuration.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants such as CY2292SL, CY2292SI, or CY2292SXI depending on voltage and temperature requirements. Field-programmable equivalents like CY2292F series may be used if on-site reprogramming capability is needed.
