181M-53LFT

Overview

The 181M-53LFT is a Spread Spectrum Clock Generator IC manufactured by Renesas Electronics Corporation. It operates at a maximum frequency of 75MHz and is housed in an 8-SOIC package. The device generates a low EMI output clock from a clock or crystal input using a proprietary mix of analog and digital Phase Locked Loop (PLL) technology.

Feature Summary

• Generates low EMI output clocks from standard clock or crystal inputs
• Utilizes proprietary analog and digital Phase Locked Loop technology for timing generation

Applications

• Timing and clock generation applications
• Systems requiring low electromagnetic interference clock signals

Procurement Notes

Verify the manufacturer designation, as this component originates from IDT which is now part of Renesas Electronics Corporation. Confirm the specific suffix 'LFT' corresponds to the correct tape and reel packaging configuration. Ensure the datasheet matches the 8-SOIC package type and 75MHz operational limit before procurement.

Selection Notes

Select this component when a low EMI clock solution is required for systems operating up to 75MHz. Consider the 8-SOIC package constraints and the need for crystal or clock input compatibility. Evaluate the proprietary PLL technology benefits against system noise sensitivity requirements.

Part Context

This component belongs to the 181M series of clock generators. It is related to variants such as the 181M-52LFT, which shares similar low EMI characteristics but may differ in specific frequency or configuration parameters. The series addresses timing needs in electronics requiring reduced electromagnetic interference.
