PY28323BPVC

Overview

The CY28323BPVC is a clock generator designed for Intel Pentium 4 CPU and chipset applications. It operates as a frequency translation generator (FTG) to provide specific timing signals required by the processor architecture. The device utilizes CMOS technology and is housed in a 48-pin SSOP package. It supports a maximum output clock frequency of 100 MHz, with a nominal crystal input frequency of 14.318 MHz. The component functions within a commercial temperature range and requires a supply voltage nominally at 3.3 V.

Feature Summary

• Provides dedicated clock signals tailored for Intel Pentium 4 processors and associated chipsets
• Generates precise timing outputs using a single external crystal reference
• Integrates necessary frequency translation logic for system synchronization

Applications

• Intel Pentium 4 CPU clock generation
• Pentium 4 chipset timing distribution
• Motherboard main clock circuitry design

Procurement Notes

Verify the manufacturer origin, noting that Cypress Semiconductor was acquired by Infineon Technologies. Confirm the package type matches the 48-pin SSOP specification. Ensure the part number suffix corresponds to the correct tape-and-reel or tube configuration if applicable. Check for RoHS compliance status relative to the production date. Validate authenticity through official distributor channels to avoid counterfeit components.

Selection Notes

Select this component specifically for legacy systems requiring compatibility with Intel Pentium 4 architectures. It is suitable for designs needing a 100 MHz output derived from a standard 14.318 MHz crystal. Consider the SSOP-48 footprint constraints during PCB layout. This device is appropriate for commercial-grade temperature environments where high-frequency jitter performance is not the primary constraint compared to cost-effective signal generation.

Part Context

This part belongs to the CY2832x family of clock generators developed for desktop computing platforms. These devices were engineered to replace discrete oscillator solutions, simplifying board design for Pentium 4-based motherboards. The family includes variants supporting different output configurations and packaging options to accommodate various motherboard form factors and assembly requirements.

Replacement Considerations

Direct substitutes include CY28323B, CY28323BPVCT, and SpectraLinear Inc CY28323PVC. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part maintains support for the specific Intel Pentium 4 chipset requirements.
