CY2292SL-1N2

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SL-1N2 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 supports configurable 3.3 V or 5.0 V operation. The device provides four independent configurable outputs (CLKA–CLKD), one CPU frequency clock (CPUCLK), and a buffered reference output (XBUF). It accepts an external crystal input between 10 MHz and 25 MHz or an external reference clock from 1 MHz to 30 MHz. In commercial temperature ranges at 3.3 V, the maximum output frequency reaches 80 MHz.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs: System PLL (SPLL), CPU PLL (CPLL), and Utility PLL (UPLL)
• EPROM programmability with factory customization options
• Low-skew, low-jitter outputs with less than 500 ps skew for heavily loaded signals
• Smooth slewing capability on CPUCLK output for power management

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Synchronous system timing
• Low-power application clocking

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific suffix '1N2' corresponds to the requested custom frequency configuration and pinout. Factory-programmed parts require submission of frequency requirements via CyClocks software to a local sales representative or field application engineer prior to ordering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part for applications requiring up to three distinct custom frequencies derived from a single source. Ensure the operating voltage matches the 3.3 V or 5.0 V requirement, as output frequency limits vary by voltage. Verify that the required output frequencies fall within the 76.923 kHz to 80 MHz range for 3.3 V commercial 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 under the Infineon product portfolio following the acquisition of Cypress Semiconductor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

CY2292SC-XXX variants offer similar functionality but support higher frequencies (up to 100 MHz) at 5.0 V. CY2292F series devices provide field-programmable EPROM capabilities instead of factory programming.
