CY2292FXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292FXC is a field-programmable, three-PLL general-purpose clock generator manufactured by Infineon Technologies (formerly Cypress Semiconductor). It utilizes EPROM technology for custom frequency configuration. The device operates within a commercial temperature range of 0°C to 70°C and supports both 3.3 V and 5.0 V supply voltages. It accepts an external reference crystal between 10 MHz and 25 MHz or an external reference clock from 1 MHz to 30 MHz. Maximum output frequencies reach 90 MHz at 5 V operation and 66.6 MHz at 3.3 V operation. The component is housed in a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated phase-locked loops (SPLL, CPLL, UPLL) for generating up to four configurable outputs.
• EPROM programmability allowing field customization via the Cypress FTG Programmer.
• Configurable 3.3 V or 5.0 V operation with low-skew outputs.
• Power management features including shutdown mode and suspend capability.

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Synchronous system timing
• Custom frequency synthesis from a single external source

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific application requires field-programmable EPROM capabilities rather than factory-programmed variants. Confirm voltage requirements align with the 3.3 V or 5.0 V operational limits specified in the datasheet. Ensure the design accommodates the 16-pin SOIC footprint and thermal characteristics appropriate for the commercial temperature range.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2292FXC when custom frequency generation is required without factory programming constraints. Verify that the input reference frequency falls within the 1 MHz to 30 MHz range. Check if the maximum output frequency requirements exceed the 66.6 MHz limit imposed during 3.3 V operation; if higher frequencies are needed, ensure the system supports 5.0 V logic levels.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY2292 family of three-PLL clock generators. The 'F' suffix indicates field-programmable EPROM architecture, while 'X' denotes the 16-pin SOIC package. The 'C' suffix specifies the commercial operating temperature range. This distinguishes it from factory-programmed versions (no 'F') and industrial temperature variants (suffix 'I').

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292FXC units or CY2292FXCT (tape and reel packaging). For different packages, consider CY2292FZX (TSSOP). Factory-programmed equivalents like CY2292SC or CY2292SL offer fixed frequencies but lack field programmability.
