CY22381SXI-206

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22381SXI-206 is a programmable clock generator manufactured by Cypress Semiconductor Corp. It operates on a single 3.3 V power supply and features three integrated phase-locked loops (PLLs) to drive up to three configurable output clocks. The device supports input frequencies from an external crystal or clock signal, with outputs derived via PLLs or reference frequency dividers. It utilizes Flash programmability for configuration storage and offers low-jitter performance suitable for general-purpose applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer status as Cypress Semiconductor has been acquired by Infineon Technologies. Confirm RoHS compliance and lead finish specifications against current datasheets, as legacy parts may have different environmental certifications. Check for obsolescence notices or lifecycle status updates before procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when three independent programmable clock outputs are required within an 8-pin SOIC package. Ensure the design accommodates the 3.3 V operating voltage range of 3.135 V to 3.465 V. Verify that the input source matches the supported crystal or external clock frequency ranges specified in the technical documentation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY22381 family of universal programmable clock generators. Variants such as CY22381FC and CY22381SC differ primarily in packaging, lead finish, and temperature ratings. The 'SXI' suffix typically denotes specific binning or manufacturing lot characteristics within the standard SOIC-8 form factor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY22381 variants like CY22381FC or CY22381SC if pin compatibility and electrical parameters match. Cross-reference with Infineon's updated product line for equivalent next-generation devices if Cypress stock is unavailable.
