252PMILF

Overview

The Renesas Electronics Corporation 252PMILF is a VersaClock synthesizer and jitter cleaner designed for clock signal generation. It operates within an industrial temperature range of -40°C to 85°C and utilizes a standard 3.3V power supply. The device is housed in an 8-pin SOIC package, supporting surface-mount installation. This component functions as a single-output clock generator capable of replacing multiple discrete crystals and oscillators, thereby reducing board space and system cost through integrated phase-locked loop technology.

Feature Summary

• VersaClock Synthesizer/Jitter Cleaner with PLL technology
• Industrial operating temperature range (-40°C to 85°C)
• Single output CMOS clock generation up to 200 MHz
• Field programmable via One-Time Programmable (OTP) ROM

Applications

• System clock generation for embedded processors
• Jitter cleaning for high-speed digital interfaces
• EMI reduction using spread spectrum techniques
• Replacing multiple discrete crystal oscillators

Procurement Notes

The 252PMILF is classified as obsolete or end-of-life by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning.

Selection Notes

Select the 252PMILF for applications requiring a low-cost, single-output field-programmable clock synthesizer. Ensure the design supports the 3.3V supply voltage and accommodates the SOIC-8 package footprint. Verify that the required output frequency falls within the 314 kHz to 200 MHz range supported by the internal PLL.

Part Context

This component belongs to the IDT/Renesas VersaClock family, originally developed by Integrated Device Technology (IDT). It is part of the 251/252 series of clock generators. The 'ILF' suffix typically denotes lead-free packaging compliant with RoHS standards and an industrial temperature grade, distinguishing it from commercial variants.

Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider the 251PMILF for similar functionality or explore newer VersaClock families such as the 5P35021. Verify pin compatibility and register configurations when migrating to alternative clock synthesizers.
