252M-46LF

Overview

The Renesas 252M-46LF is a clock synthesizer and spread spectrum clock generator IC. It operates at a maximum frequency of 200 MHz. The device features an integrated Phase-Locked Loop (PLL) with bypass capability. It supports both clock and crystal inputs. The output configuration includes multiple signal paths. The component is housed in an 8-SOIC package with a width of 3.90 mm.

Feature Summary

• Integrates spread spectrum clock generation functionality for noise reduction
• Includes a programmable PLL with bypass mode for flexibility
• Supports dual-output configurations from a single synthesizer core

Applications

• General clock distribution systems requiring jitter attenuation
• Digital circuits needing spread spectrum to meet EMI regulations
• Embedded systems utilizing crystal or external clock references

Procurement Notes

Verify the specific suffix and package variant against the official Renesas datasheet to ensure compatibility with your design requirements. Confirm that the 8-SOIC footprint matches your PCB layout constraints. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a low-cost, field-programmable solution is required for generating frequencies up to 200 MHz. It is suitable for applications where spread spectrum modulation is necessary to reduce electromagnetic interference. Ensure the input source matches the supported crystal or clock types specified in the technical documentation.

Part Context

This part belongs to the ICS252 family of clock synthesizers. These devices are designed as low-cost alternatives for general-purpose clock generation. They offer field-programmable capabilities to generate various output frequencies without custom mask ROM changes, providing design flexibility for mass production.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other ICS252 variants or similar Renesas clock generators by comparing pinouts and electrical specifications directly with manufacturer datasheets.
