CY22381SXI-174

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22381SXI-174 is a three-PLL general-purpose FLASH programmable clock generator manufactured by Infineon Technologies. It operates on a 3.3 V supply voltage with a range of 3.135 V to 3.465 V. The device features an industrial operating temperature range from -40°C to +85°C and is housed in an 8-pin SOIC package. It supports external reference clocks up to 166 MHz for industrial applications and generates output frequencies up to 166 MHz. Key electrical parameters include a typical power supply current of 70 mA at 166 MHz, peak-to-peak period jitter of 200 ps, and a lock time of 1.0 ms.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '174' against official Infineon documentation to confirm the exact factory-programmed frequency configuration. Ensure the ordering code matches the required industrial temperature grade and package type. Confirm availability through authorized distributors as this component may be subject to lifecycle changes or limited production runs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems requiring three independent programmable clock outputs from a single source. It serves as a functional upgrade for legacy CY2081 family designs. Consider the 8-pin SOIC package constraints and verify that the input reference frequency falls within the supported range for the desired output specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY22381 family of clock generators, originally developed by Cypress Semiconductor Corporation before its acquisition by Infineon Technologies. The series is designed to replace older programmable clock solutions with enhanced flexibility and lower power consumption options.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The CY22381FXI is a commercial-grade equivalent within the same package. For lead-free NiPdAu finish requirements, consider the CY223811FXI variant. Verify pinout compatibility and programming tool support when substituting.
