251MI-34LFT

Overview

The 251MI-34LFT is a clock/frequency synthesizer manufactured by Renesas Electronics Corporation, belonging to the VersaClock series. It operates as a single-output device with a maximum frequency of 200 MHz and utilizes Phase-Locked Loop (PLL) technology. The component supports input from crystals or clocks and provides LVCMOS outputs. It functions within a supply voltage range of 3.15 V to 3.45 V and is rated for an operating temperature between -40°C and 85°C. The device is housed in an 8-SOIC package.

Feature Summary

• Single-output field programmable clock synthesizer
• Maximum output frequency up to 200 MHz
• Supports PLL operation with crystal or clock input
• LVCMOS output interface

Applications

• General clock generation for digital systems
• Frequency synthesis in embedded applications
• Timing reference for logic circuits

Procurement Notes

Verify the specific suffix '34' against official Renesas documentation to confirm pinout and electrical characteristics, as generic 251MI listings may vary. Confirm RoHS compliance status via the manufacturer's datasheet before integration. Check current lifecycle status as this part number may be obsolete or subject to change notices.

Selection Notes

Select this component when a single LVCMOS output clock signal up to 200 MHz is required. Ensure the design accommodates the 3.15 V to 3.45 V supply voltage range. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Compare against other VersaClock variants if differential outputs or higher frequencies are needed.

Part Context

This part belongs to the Renesas VersaClock family of clock generators. These devices typically replace multiple discrete oscillators to save board space. The 251MI variant specifically denotes a single-output configuration within this product line, designed for cost-sensitive applications requiring reliable frequency synthesis.

Replacement Considerations

Consult Renesas official substitution guides for direct replacements. Generic equivalents may not match the specific PLL performance or package dimensions. Verify compatibility with existing firmware or hardware configuration registers if replacing a similar VersaClock model.
