CY25100SXC-37AT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY25100SXC-37AT 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 3 MHz to 150 MHz, generating output clocks up to 200 MHz. The device utilizes a Phase-Locked Loop (PLL) architecture with configurable spread spectrum modulation to reduce electromagnetic interference. It features a single circuit configuration with a 1:2 input-to-output ratio and accepts CMOS or crystal inputs. The component is housed in an 8-SOIC package with a width of 3.90mm and is rated for an operating temperature range of -40°C to 85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '37AT' against official Cypress documentation to confirm the exact factory-programmed frequency and modulation parameters, as these are fixed at manufacture. Ensure compatibility with the required input crystal frequency and check for RoHS compliance status relative to current environmental regulations before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency, low-cost solution is preferred over fully reprogrammable variants. Confirm that the pre-programmed output frequency matches the target application requirements exactly. Verify that the 8-SOIC package dimensions fit the PCB layout constraints and that the 3.3V nominal supply voltage aligns with the system power design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY25100 VersaClock family of spread spectrum clock generators. It shares architectural similarities with other members like the CY25100ZIF but differs in its field-programmable nature and specific factory-set parameters. The series is designed to simplify clock tree designs by integrating synthesis and jitter attenuation capabilities into a single small-footprint IC.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers for the CY25100SXC-37AT were not identified in the provided source material. Cross-referencing with generic CY25100 family members requires verification of matching factory-programmed frequencies and modulation profiles.
