CY22801KFXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22801KFXC is a Universal Programmable Clock Generator (UPCG) manufactured by Infineon Technologies. It features an integrated phase-locked loop (PLL) and supports field-programmable input frequencies ranging from 8 MHz to 30 MHz for crystal inputs, and 1 MHz to 133 MHz for external clock inputs. The device generates low-voltage complementary metal oxide semiconductor (LVCMOS) outputs with frequencies up to 200 MHz in commercial grade applications. It operates on a single 3.3 V supply voltage within the 0°C to +70°C temperature range. The component is housed in an 8-pin small-outline integrated circuit (SOIC) package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix KFXC against official Infineon documentation to confirm the exact temperature grade and packaging configuration. Ensure compatibility with programming tools such as the CY36800 dongle or third-party programmers for initial configuration. Confirm that the selected variant meets the required commercial operating temperature range of 0°C to +70°C for your specific application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a flash-programmable clock generator with up to three outputs is required. Consider the CY22801 if design flexibility allows for post-manufacturing frequency adjustments using CyClocksRT software. Evaluate the need for spread spectrum capabilities to mitigate electromagnetic interference. Verify that the input reference frequency falls within the specified crystal or driven clock ranges before finalizing the part selection.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY22801 belongs to the InstaClock series of universal programmable clock generators originally developed by Cypress Semiconductor, now part of Infineon Technologies. This family is designed to replace multiple fixed-frequency clock generators, simplifying inventory management. The CY22801 specifically offers enhanced versatility through its proprietary PLL and support for various modulation profiles, making it suitable for diverse timing requirements in modern electronic designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements should be sought within the CY22801 family, such as industrial grade variants like CY22801KSXC. Verify pinout compatibility and electrical specifications, particularly the operating temperature range and output frequency limits, before substituting. Consult official cross-reference lists for any updated revisions or alternative packages offered by Infineon.
