CY2292FZXKN

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292FZXKN is a field-programmable, three-PLL general-purpose clock generator manufactured by Infineon Technologies (formerly Cypress Semiconductor). It utilizes EPROM technology for customizable frequency generation from a single external source. The device supports configurable 3.3 V or 5 V operation and provides low-skew, low-jitter outputs. It features power management options including shutdown, output enable, and suspend modes. The component is housed in a 16-pin TSSOP package and operates within a commercial temperature range of 0°C to 70°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated phase-locked loops (CPLL, SPLL, UPLL) for generating up to three custom frequencies
• EPROM programmability allowing field customization via the Cypress FTG Programmer
• Smooth slewing capability on the CPUCLK output between 20 MHz and maximum frequency limits
• Configurable power saving features including shutdown, OE, and suspend modes

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Synchronous system timing
• Low-power green applications requiring frequency slewing

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the 'KN' suffix corresponds to the standard CY2292FZX ordering code defined in the datasheet. Confirm the specific programming status required, as the base model is field-programmable. Ensure compatibility with the Cypress FTG Programmer (CY3670) and adapter (CY3095) if field configuration is necessary.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when EPROM-based field programmability is required for the CY2292 family. Choose the FZX variant specifically for the 16-pin TSSOP package format. Verify voltage requirements, as output frequency ranges differ between 3.3 V and 5 V operation modes. Ensure the application falls within the commercial temperature range (0°C to 70°C).

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 series is a third-generation clock generator family upwardly compatible with industry standards ICD2023 and ICD2028. The product line includes factory-programmable (blank suffix) and field-programmable ('F' suffix) options. The manufacturer transitioned from Cypress Semiconductor Corporation to Infineon Technologies, which continues to support existing part numbers.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants such as CY2292FXC (SOIC package) or CY2292FXI (Industrial temperature). Field-programmable alternatives like CY2292FZXT (Tape and Reel) are also available.
