CY25100SXC-064

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25100SXC-064 is a field and factory programmable spread spectrum clock generator designed for EMI reduction. It operates on a single 3.3 V supply within the commercial temperature range of 0 °C to 70 °C. The device synthesizes output frequencies from 3 MHz to 200 MHz using an integrated PLL, accepting input clocks or crystals between 8 MHz and 166 MHz. It features programmable center spread (±0.25% to ±2.5%) and down spread (-0.5% to -5.0%) with a nominal modulation frequency of 31.5 kHz. The component includes internal load capacitor tuning arrays ranging from 12 pF to 60 pF, eliminating external crystal capacitors. It provides two outputs: a non-spread REFCLK and a modulated SSCLK.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrates a proprietary Phase-Locked Loop and Spread Spectrum Clock technology to synthesize and modulate input clock frequencies, significantly reducing radiated electromagnetic interference energy at fundamental and harmonic frequencies.
• Features programmable configuration memory allowing customization of output frequency, spread percentage, crystal load capacitance, reference clock enablement, and power-down or output-enable functions prior to installation.
• Includes internal programmable load capacitor tuning arrays that match crystal load requirements, removing the need for external capacitors on the XIN and XOUT pins.

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed digital electronic systems requiring EMI noise reduction
• LCD driver ICs utilizing spread spectrum clock generators
• Applications needing replacement of multiple discrete crystals and oscillators

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '064' against official Infineon/Cypress ordering documentation to confirm the exact programmed configuration parameters. Factory-programmed variants require submission of requests to local Field Application Engineers or sales representatives. Confirm package type availability matches design requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when system-level EMI compliance requires active frequency modulation of clock signals. Ensure the required output frequency falls within the 3 MHz to 200 MHz range and the input source supports the specified 8 MHz to 166 MHz range. Verify that the 3.3 V operating voltage aligns with the target system power rails.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY25100 series serves as a versatile clock synthesis solution for embedded processors and controllers. It replaces multiple discrete timing components, saving board space and cost. The device supports both field programmability for prototyping via the CY3672 programmer and factory programming for high-volume production runs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY25100 variants such as CY25100SXCF or CY25100ZXIF, provided the programmed configuration matches the application requirements. Cross-family substitutes like the 5P35021 offer similar functionality but may differ in package dimensions and programming interfaces.
