251MI-38LF

Overview

The Renesas Electronics Corporation 251MI-38LF is a field-programmable VersaClock synthesizer housed in an 8-pin SOIC package. It operates within a supply voltage range of 3.15V to 3.45V and supports input frequencies from 3MHz to 150MHz, generating outputs up to 200MHz. The device features four addressable configuration registers and utilizes a Phase-Locked Loop (PLL) architecture. It includes spread spectrum clock generation capabilities to reduce electromagnetic interference. The component functions as a single-output clock generator designed to replace multiple discrete oscillators.

Feature Summary

Field programmability via OTP ROM and configurable registers
Integrated PLL for frequency synthesis from standard crystal inputs
Spread spectrum modulation capability for EMI reduction

Applications

System-level clock generation replacing discrete oscillators
Low-cost single-output clock distribution
Applications requiring spread spectrum techniques for EMI mitigation

Procurement Notes

Verify the specific suffix designation against the manufacturer's current product lifecycle status, as this part number may be obsolete or superseded by newer VersaClock series components. Confirm that the required output frequency and input reference specifications align with the device's operational limits before finalizing procurement. Ensure compatibility with the intended system voltage and temperature range requirements.

Selection Notes

Select this component when a single-output, low-cost clock solution is required to replace multiple crystals or oscillators. It is suitable for designs needing programmable frequency synthesis with spread spectrum features. Consider alternative active parts if long-term availability is critical, given the potential obsolete status of this specific model variant.

Part Context

This component belongs to the VersaClock family of clock synthesizers manufactured by Renesas Electronics. These devices are designed to provide flexible clock generation using PLL technology. The 251MI series specifically targets applications requiring field programmability and EMI reduction through spread spectrum modulation, offering a compact alternative to traditional oscillator solutions.
