CY2292SXL-1J5

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SXL-1J5 is a factory-programmable, three-PLL general-purpose clock generator manufactured by Cypress Semiconductor. It operates at 3.3 V with a commercial temperature range of 0°C to 70°C and utilizes EPROM technology for frequency customization. The device provides four configurable outputs (CLKA–CLKD) and a CPUCLK output, supporting frequencies from 76.923 kHz up to 80 MHz. It accepts a 10 MHz to 25 MHz external crystal or a 1 MHz to 30 MHz reference clock. Key features include low-skew outputs, smooth CPUCLK slewing between 20 MHz and the maximum frequency, and power management via shutdown and suspend modes.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated phase-locked loops (CPLL, SPLL, UPLL) for generating up to eight user-selectable CPU frequencies and multiple fixed outputs.
• EPROM programmability allows for custom frequency configurations with low skew (less than 500 ps) across outputs.
• Smooth slewing capability on the CPUCLK output enables dynamic frequency transitions for power savings.
• Configurable 3.3 V operation with dedicated shutdown and suspend inputs to minimize power consumption.

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Synchronous system timing
• Low-power embedded designs

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific suffix '1J5' corresponds to the exact factory-programmed frequency configuration required. As this is a custom part, standard ordering codes like CY2292SXL require a three-digit extension to define the pinout and frequencies. Confirm compatibility with the 3.3 V supply voltage and commercial temperature range specified in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY2292SXL variant specifically for 3.3 V applications within the commercial temperature range. Ensure the design requires factory programming rather than field programmability (CY2292F). Verify that the required output frequencies fall within the 76.923 kHz to 80 MHz range for 3.3 V operation. Consider the 16-pin SOIC package constraints if board space is limited.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 series is upwardly compatible with industry-standard ICD2023 and ICD2028 devices. It belongs to the third-generation family of clock generators designed for high configurability in modern motherboards. Infineon Technologies continues to offer this product as part of its portfolio following the acquisition of Cypress Semiconductor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must match the 3.3 V operation, commercial temperature range, and factory-programmed nature. Field-programmable equivalents like the CY2292FXL are functionally similar but differ in programmability. Cross-family members such as the CY2291SL share the same package but have different PLL architectures and should be evaluated carefully.
