271PGILFT

Overview

The Renesas Electronics Corporation 271PGILFT is a field-programmable VCXO clock synthesizer and fanout buffer. It generates up to six high-quality, high-frequency clock outputs from multiple reference inputs. The device integrates triple phase-locked loops (PLLs) for flexible frequency synthesis. It operates as a versatile solution for distributing precise timing signals in complex electronic systems requiring low jitter and programmable output configurations.

Feature Summary

• Integrates triple phase-locked loops for advanced clock generation
• Generates up to six distinct high-frequency clock outputs
• Supports field programming for customized frequency synthesis
• Functions as both a synthesizer and a fanout buffer

Applications

• Telecommunications infrastructure timing distribution
• High-speed data converter clocking systems
• Test and measurement equipment signal generation
• Network synchronization applications

Procurement Notes

Verify the specific revision level and package marking against the official Renesas datasheet before integration. Confirm that the lead-free finish and RoHS compliance meet current environmental regulations for your region. Ensure that the ESD handling procedures are strictly followed during storage and assembly to prevent damage to the sensitive internal circuitry of the component.

Selection Notes

Select this component when multiple synchronized clock domains with varying frequencies are required from a single source. It is suitable for designs needing low jitter performance and programmable output ratios. Consider the power supply requirements and thermal characteristics relative to the system's overall power budget and enclosure constraints.

Part Context

This part belongs to the VersaClock family of clock generators. It serves as a critical timing element in systems where precise frequency control and distribution are paramount. The device replaces discrete PLL and buffer solutions, reducing board space and design complexity while improving signal integrity through integrated on-chip filtering.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing firmware or configuration tools if considering alternative devices from other manufacturers.
