CY2292EFXC

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 customizable frequency generation. The device supports input frequencies from 1 MHz to 30 MHz via an external reference clock or 10 MHz to 25 MHz via a crystal. It provides four configurable outputs: CPUCLK, CLKA, CLKB, and CLKC. In commercial temperature ranges with 3.3 V operation, the maximum output frequency reaches 66.6 MHz; with 5.0 V operation, it reaches 90 MHz. 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 flexible clock synthesis
• EPROM programmability allowing field customization using the Cypress FTG Programmer
• CPUCLK smooth slewing capability between 20 MHz and maximum output frequency for power management
• Configurable 3.3 V or 5.0 V supply voltage operation

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 the specific ordering suffix to confirm package type and temperature range. The 'C' suffix indicates a 16-pin SOIC package with commercial operating temperature (0°C to 70°C). Confirm whether tape-and-reel packaging is required by checking for the 'T' suffix (CY2292FXCT). Ensure the design supports field programming if utilizing the EPROM capabilities rather than factory configuration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2292FXC when field programmability is required for custom clock frequencies. Verify that the target application operates within the commercial temperature range of 0°C to 70°C. For industrial applications (-40°C to 85°C), the CY2292FXI variant must be selected instead. Ensure the system voltage aligns with the supported 3.3 V or 5.0 V options and that the required output frequencies fall within the specified limits for the chosen voltage.
