CY25100SXC-004AT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25100SXC-004AT is a field-programmable spread spectrum clock generator manufactured by Cypress Semiconductor Corp. It operates within a supply voltage range of 3.13V to 3.45V and supports input frequencies from 5 MHz to 27 MHz via crystal or CMOS sources. The device generates output clock frequencies up to 200 MHz with a 1:2 input-to-output ratio. It utilizes an internal Phase-Locked Loop (PLL) for frequency synthesis and includes configurable registers for spread spectrum modulation to reduce electromagnetic interference. The component is housed in an 8-SOIC package and functions reliably across a temperature range of -40°C to 85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '004AT' against official Cypress documentation to confirm the exact factory programming parameters, as this identifier denotes the custom frequency and modulation settings. Ensure compatibility with the required 3.3V logic levels and check for RoHS compliance status relative to current environmental regulations before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-chip solution is needed to generate multiple clock outputs from one reference source while actively managing EMI. It is suitable for designs requiring programmability in the field or for low-volume production runs where custom mask-programmed devices are cost-prohibitive. Confirm that the maximum output frequency requirement does not exceed 200 MHz.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the VersaClock family of programmable clock synthesizers from Cypress Semiconductor. These devices are engineered to replace fixed-frequency oscillators in complex digital systems. The CY25100 series specifically targets applications needing flexible frequency generation and spread spectrum capabilities within a compact surface-mount package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers for this specific model variant are not available in verified sources. Cross-referencing requires matching the exact output frequency and spread spectrum profile defined by the '004AT' suffix, which may necessitate consulting the manufacturer for direct equivalents.
