252M-43LFT

Overview

The Renesas 252M-43LFT is a field-programmable clock synthesizer IC designed for precise frequency control applications. It generates dual output frequencies ranging from 314 kHz to 200 MHz using an internal phase-locked loop (PLL) and frequency synthesis architecture. The device accepts a single reference input to produce synchronized clock signals, ensuring low jitter and stable timing performance for downstream digital components in communication and data processing systems.

Feature Summary

• Dual-output clock generation capability
• Field-programmable frequency synthesis
• Integrated phase-locked loop (PLL)
• Low jitter output signal stability

Applications

• Communication equipment clock distribution
• Data processing system timing synchronization
• Network interface card clock generation
• Industrial control system timing

Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the operating voltage and reference input requirements match your system design. Ensure the programming tool or method aligns with the manufacturer's specifications for field programmability. Check for any end-of-life notifications or alternative part recommendations from Renesas Electronics.

Selection Notes

Select this component when dual independent clock outputs are required from a single reference source. Consider its frequency range limits and jitter specifications relative to your target application's sensitivity. Evaluate the programming flexibility needs against fixed-frequency alternatives. Ensure thermal and power constraints fit within the device's operational envelope.

Part Context

The 252M-43LFT belongs to the ICS252 family of clock generators. This series provides cost-effective solutions for generating multiple clock frequencies from a single input. It is commonly used in scenarios requiring precise timing without complex external circuitry, offering a compact alternative to discrete PLL designs.

Replacement Considerations

Check for direct cross-reference parts such as the ICS252MI-47LFT if different frequency ranges or packaging options are needed. Verify compatibility with existing board layouts and programming interfaces before substitution.
