CY2292SL-1W5

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SL-1W5 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 and provides four independent configurable outputs alongside a CPUCLK output with smooth slewing capabilities. Input frequencies are derived from an external crystal (10 MHz to 25 MHz) or reference clock (1 MHz to 30 MHz).

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs: System PLL (SPLL), CPU PLL (CPLL), and Utility PLL (UPLL)
• EPROM programmability for custom frequency generation
• Configurable 3.3 V or 5.0 V operation
• Smooth slewing on CPUCLK output

Clock Generators, PLLs, Frequency Synthesizers Applications

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

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '1W5' against official Infineon/Cypress ordering documentation to confirm the exact factory-programmed pinout and frequency configuration. Factory-programmed devices require submission of custom requests via CyClocks software to a local FAE.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for designs requiring up to three distinct custom frequencies derived from a single external source. Ensure the required output frequencies fall within the 76.923 kHz to 80 MHz range for 3.3 V commercial operation. Verify compatibility with downstream PLL locking requirements using the CPUCLK smooth slewing feature.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY2292 family of three-PLL EPROM-programmable clock generators. It is upwardly compatible with industry-standard ICD2023 and ICD2028 devices. The product line is now managed by Infineon Technologies following the acquisition of Cypress Semiconductor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants such as CY2292SC, CY2292SI, or CY2292FXC depending on voltage and temperature requirements. Field-programmable equivalents like CY2292FZX offer similar functionality but require in-field programming.
