CY22050FC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22050FC is a one-PLL general-purpose flash-programmable clock generator housed in a 16-pin TSSOP package. It operates on a 3.3 V supply with an optional 2.5 V output level. The device accepts an input frequency range of 8 MHz to 30 MHz via external crystal or 1 MHz to 133 MHz via driven clock. Output frequencies reach up to 200 MHz at 3.3 V and 166.6 MHz at 2.5 V for commercial temperature ranges, while industrial ranges support up to 166.6 MHz (3.3 V) and 150 MHz (2.5 V). It provides six configurable outputs with low skew and jitter characteristics.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'FC' against official ordering tables, as standard listings typically use 'KFI' for industrial or 'KFZXC' for commercial variants. Confirm that the component matches the original Cypress Semiconductor specifications now managed under Infineon Technologies. Ensure compatibility with the CyberClocks software for programming configuration files before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single PLL solution is required for up to six independent clock outputs. Consider the CY22050FC if field programmability is necessary for design iterations or inventory management. Evaluate the input frequency requirements to ensure they fall within the specified crystal or driven clock ranges. Verify that the thermal environment aligns with either commercial or industrial operating temperature limits.

Clock Generators, PLLs, Frequency Synthesizers Part Context

Originally developed by Cypress Semiconductor Corporation, this device belongs to the CyberClocks family of programmable clock generators. Following corporate acquisitions, the product line and associated documentation are now maintained by Infineon Technologies. The part represents a legacy general-purpose solution designed for flexibility in system clocking architectures without requiring complex external components.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include CY22050KFI for industrial temperature ranges and CY22050KFZXC for commercial ranges. Factory-programmed variants such as CY22050ZXC-xxx may serve as alternatives if field programming is not required. Verify pinout compatibility and electrical characteristics before replacing existing designs.
