CY2292AZL-101

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2292AZL-101 is a three-phase-locked-loop (PLL) general-purpose EPROM-programmable clock generator manufactured by Cypress Semiconductor. It generates up to three custom frequencies from one external source, supporting factory or field programmability. The device features low-skew, low-jitter outputs and configurable 3.3 V or 5 V operation. It includes power management options such as shutdown, output enable, and suspend modes. The unit operates within a commercial temperature range of 0°C to 70°C and utilizes a 16-pin SOIC package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Three integrated PLLs: System PLL (SPLL), CPU PLL (CPLL), and Utility PLL (UPLL).
• EPROM programmability for customized frequency generation.
• Configurable 3.3 V or 5 V supply voltage operation.
• Smooth slewing on the CPUCLK output for power savings.

Clock Generators, PLLs, Frequency Synthesizers Applications

• PC motherboard clock generation.
• Synchronous system timing applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'AZL' against official Infineon/Cypress ordering documentation. Standard part numbers in the datasheet use suffixes like SC, SL, SXC, SXL, FXC, FXI, FZX, or FZXI. Confirm if 'AZL' denotes a specific factory-programmed configuration code or an obsolete variant before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select based on required operating voltage (3.3 V or 5 V) and temperature range (Commercial 0–70°C or Industrial -40–85°C). Determine if factory programming (CY2292) or field programmability (CY2292F) is needed. Ensure the desired output frequencies fall within the supported ranges: up to 100 MHz at 5 V or 80 MHz at 3.3 V for commercial parts.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY2292 is part of the third-generation family of clock generators, upwardly compatible with industry standards ICD2023 and ICD2028. Cypress Semiconductor Corporation was acquired by Infineon Technologies, which continues to offer the product under the Infineon portfolio while maintaining original document content and ordering part numbers.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements depend on the specific frequencies programmed into the EPROM. For generic CY2292 functionality, consider other CY2292 variants (e.g., CY2292SC, CY2292FXC) matching the voltage and temperature requirements. Field-programmable versions (CY2292F) require the Cypress FTG Programmer (CY3670) for reconfiguration.
