CY2292SC-984

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292SC-984 is a factory-programmable, three-PLL general-purpose clock generator in a 16-pin SOIC package. It generates up to six configurable output frequencies from an external crystal (10–25 MHz) or reference clock (1–30 MHz). The device supports 5V operation with output frequencies ranging from 76.923 kHz to 100 MHz. Key electrical parameters include a maximum supply current of 100 mA at 5V and less than 50 µA in shutdown mode. Outputs exhibit low skew (≤ 0.5 ns) and peak-to-peak jitter under 350 ps.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated Phase-Locked Loops (SPLL, CPLL, UPLL) for flexible frequency generation
• EPROM programmability allowing custom frequency configurations
• Smooth slewing capability on CPUCLK between 20 MHz and maximum output frequency
• Configurable power management via Shutdown/OE and Suspend inputs

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation
• Laptop and Green PC applications requiring power savings
• Systems compatible with ICD2023 and ICD2028 standards

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific 984 suffix configuration against the official Cypress datasheet to confirm exact pinout and frequency assignments. Confirm that the 16-pin SOIC package matches the design requirements. Ensure the commercial temperature range (0°C to +70°C) aligns with the system environment. Check for lead-free compliance if required by assembly specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when factory programming is preferred over field programming. Choose the 5V variant (SC series) for systems requiring up to 100 MHz output. Consider the CY2292F series if field reprogrammability is needed. Verify that the input source matches the supported crystal or reference clock ranges.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 belongs to the third-generation FleXO family of clock generators. It is upwardly compatible with industry-standard ICD2023 and ICD2028 devices. The SC suffix denotes a factory-programmable version in a standard SOIC package operating at 5V.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other CY2292 variants such as CY2292SL for 3.3V operation or CY2292FI for industrial temperature ranges. Field-programmable equivalents like CY2292F may require software reconfiguration.
