CY2292FZX

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292FZX 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. The device operates on a single supply voltage of either 3.0 V to 3.6 V or 4.5 V to 5.5 V. It accepts an external reference crystal in the 10 MHz to 25 MHz range or an external reference clock between 1 MHz and 30 MHz. Output frequencies are configurable from 76.923 kHz up to 90 MHz at 5 V operation, or up to 66.6 MHz at 3.3 V operation. The component is housed in a 16-pin TSSOP package and supports commercial temperature ranges from 0°C to +70°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated phase-locked loops (SPLL, CPLL, UPLL) for flexible clock generation
• EPROM programmability allowing field customization via CyClocks software and FTG programmer
• Configurable 3.3 V or 5 V operation with low-skew CMOS outputs
• Power management features including shutdown mode (<50 µA current) and suspend capability

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Synchronous system timing
• Custom frequency synthesis for embedded processors

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. The 'Z' suffix indicates a 16-pin TSSOP package, while 'C' denotes commercial temperature range. Confirm whether tape-and-reel packaging is needed by checking for the 'T' suffix (CY2292FZXT). Ensure compatibility with the Cypress FTG Programmer (CY3670) and adapter (CY3095) if field programming is planned.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2292FZX when field programmability is required rather than factory-programmed variants. Choose this model over the SOIC version (CY2292FXC) if a smaller footprint is necessary. Verify that the maximum output frequency requirements do not exceed 90 MHz at 5 V or 66.6 MHz at 3.3 V. Consider the CY2292FZXI variant if industrial temperature operation (-40°C to +85°C) is required.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292FZX belongs to the CY2292 family of three-PLL clock generators. It is functionally compatible with industry-standard ICD2023 and ICD2028 devices. The part is currently supported under the Infineon Technologies portfolio following the acquisition of Cypress Semiconductor. It serves as a drop-in replacement for legacy clock generators in systems requiring customizable CPU and peripheral clocks.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

For direct pin-compatible replacements, consider the CY2292FXC (SOIC package) or CY2292FZXI (Industrial temperature). Factory-programmable versions like CY2292SC or CY2292SI offer similar electrical characteristics but lack field programmability.
