251M-24LFT

Overview

The 251M-24LFT is a clock generator, PLL, and frequency synthesizer IC manufactured by Renesas Electronics Corporation. It provides precise timing solutions for applications requiring accurate frequency control. The device operates within a supply voltage range of 2.97V to 3.63V and supports a maximum frequency of 175MHz. It features a 1:10 input-to-output ratio with no differential inputs or outputs. The component is housed in a 24-TSSOP package (0.173", 4.40mm width) and is designed for surface mount installation. It functions as a clock driver and fanout distribution unit with spread spectrum capabilities.

Feature Summary

• Integrates spread spectrum clock generation technology for noise reduction
• Provides fanout distribution with a 1:10 input to output ratio
• Operates as a CMOS output clock driver

Applications

• Systems requiring precise timing and clock distribution
• Applications needing spread spectrum clock generation for EMI reduction
• Fanout distribution circuits in digital systems

Procurement Notes

Verify the specific suffix 'LFT' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices as this component may be discontinued. Ensure the 24-TSSOP package dimensions match your PCB footprint requirements before procurement.

Selection Notes

Select this component when a single clock source needs to drive multiple loads with a 1:10 ratio. It is suitable for designs operating between 2.97V and 3.63V. Consider the 175MHz maximum frequency limit for high-speed applications. Verify that the non-differential input/output configuration meets your system's signal integrity requirements.

Part Context

This part belongs to the 251M series of clock/timing ICs from Renesas. It serves as a specialized solution for generating and distributing clock signals with spread spectrum capabilities. The device complements other timing components by providing robust fanout distribution in a compact TSSOP package.
