281PGILFT

Overview

The Renesas 281PGILFT is a VersaClock triple PLL field programmable spread spectrum clock synthesizer. It generates up to three high-quality, high-frequency clock outputs with multiple reference edges. The device operates at frequencies up to 200MHz and is housed in a 16-TSSOP package measuring 0.173 inches (4.40mm) in width. This component provides precise timing solutions for systems requiring flexible clock distribution.

Feature Summary

• Triple phase-locked loop architecture for independent clock generation
• Field programmable spread spectrum capability to reduce electromagnetic interference
• Supports multiple reference edges for versatile system integration

Applications

• High-frequency clock distribution networks
• Systems requiring spread spectrum clocking for EMI reduction
• Digital signal processing equipment requiring precise timing references

Procurement Notes

Verify the exact suffix against official Renesas documentation to ensure correct package type and temperature range specifications. Confirm that the field-programmable configuration requirements align with your design tools. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards and pinout definitions before finalizing procurement orders.

Selection Notes

Select this component when a single IC must provide multiple distinct clock outputs with spread spectrum functionality. The triple PLL design allows for independent frequency control of each output channel. Consider the 16-TSSOP package constraints for PCB layout space. Ensure the input reference source matches the device's operational voltage and frequency requirements.

Part Context

This part belongs to the Renesas VersaClock family of clock generators. These devices are designed to replace fixed-frequency oscillators and jitter cleaners in complex digital systems. The 281 series specifically targets applications needing flexible, multi-output timing solutions with programmable spread spectrum features to meet stringent electromagnetic compatibility standards.

Replacement Considerations

Check official cross-reference lists for direct replacements. Verify pin-to-pin compatibility if substituting with other VersaClock models. Ensure the replacement supports the same number of PLLs and output channels. Confirm that the new part maintains the required spread spectrum modulation depth and frequency range.
