CY22394KFXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22394KFXC is a programmable PLL clock generator manufactured by Infineon Technologies, formerly Cypress Semiconductor. It integrates three independent PLL circuits within a single TSSOP-16 package. The device supports input frequencies ranging from 1 MHz to 166 MHz and generates output frequencies between 100 MHz and 400 MHz. It operates on a 3.3V power supply with a voltage range of 3.135 V to 3.465 V. Designed for low-power applications, it utilizes Silicon technology and functions within a commercial temperature range of 0°C to +70°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer designation as Infineon Technologies, as Cypress Semiconductor was acquired. Confirm the specific suffix 'KFXC' matches the required tape-and-reel or tube packaging configuration. Check RoHS compliance status against current environmental regulations. Ensure the component meets the specified 0°C to +70°C operating temperature range for the target application environment.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple independent clock outputs are required from a single source. The 166 MHz maximum input frequency limits suitability for higher-frequency references. Verify that the 100 MHz to 400 MHz output range covers all system requirements. The TSSOP-16 package requires appropriate PCB footprint design for surface-mount assembly.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY2239x family of programmable clock generators. These devices are designed to replace fixed-frequency oscillators and discrete PLL solutions. The family offers flexibility in frequency planning through internal programming registers. The CY22394 variant specifically provides three PLL channels for complex clocking architectures.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other CY22394 variants with different suffixes indicating package or temperature variations. Cross-reference with CY22393 or CY22395 if fewer or more PLL channels are acceptable. Verify pin compatibility before replacing with generic PLL ICs.
