CY2292SL-1T3

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SL-1T3 is a Three-PLL General-Purpose EPROM Programmable Clock Generator manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates in Commercial temperature range with 3.3V supply voltage and features a 16-pin SOIC package. The device generates up to six configurable clock outputs from external sources, supporting input frequencies of 10 MHz–25 MHz via crystal or 1 MHz–30 MHz via reference clock. Output frequency ranges extend from 76.923 kHz to 80 MHz at 3.3V operation. Key electrical characteristics include low-skew outputs (≤ 500 ps), smooth CPUCLK slewing between 20 MHz and maximum output frequency, and power management options including shutdown and suspend modes.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix '1T3' against official Infineon/Cypress documentation to confirm tape-and-reel packaging and exact frequency configuration. Ensure compatibility with 3.3V commercial temperature requirements. Check for end-of-life status as this component family may be discontinued.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when three independent PLLs are required for complex clock tree generation. Verify that the EPROM programmability meets long-term production needs without field reprogramming. Confirm that the 16-pin SOIC package fits the board layout constraints and that the 3.3V operating voltage aligns with the system power rails.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 series is an upwardly compatible successor to industry standard ICD2023 and ICD2028 devices. It provides a high level of customizable features for modern motherboards. The SL suffix specifically denotes the 3.3V commercial temperature variant in the 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements depend on the specific programmed frequencies. Generic family members like CY2292SC-XXX (5V) or CY2292SI-XXX (Industrial) share the same pinout but differ in voltage or temperature rating. Field-programmable variants like CY2292F require different programming tools.
