82V3398NLG8

Overview

The 82V3398NLG8 is a Synchronous Ethernet WAN Phase-Locked Loop (PLL) manufactured by Renesas Electronics. It operates within a maximum input frequency of 625 MHz and provides an output frequency range centered at 644.5312 MHz. The device utilizes Silicon Integrated Systems (Si) technology and supports multiple input levels including AMI, LVCMOS, LVDS, and LVPECL. It is housed in a 72-pin VFQFPN package designed for surface mount applications. The component functions as a dedicated clock generator for network synchronization standards.

Feature Summary

• Generates node clocks compliant with ITU-T G.8261 and G.8262 Synchronous Ethernet standards
• Features adjustable bandwidth ranging from 0.5 mHz to 560 Hz for precise jitter filtering
• Supports diverse input signal levels including LVDS, LVPECL, LVCMOS, and AMI

Applications

• Synchronous Ethernet WAN network infrastructure
• SONET/SDH timing distribution systems
• ITU-T G.8261/G.8262 compliant clock generation nodes

Procurement Notes

Verify the specific ordering suffix and package variant against the official Renesas datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure the procurement channel provides original factory-sealed components to maintain signal integrity and reliability standards.

Selection Notes

Select this component when designing systems requiring strict adherence to ITU-T G.8261 or G.8262 synchronization standards. The device is suitable for applications needing a single-chip PLL solution with flexible input level support. Consider the 72-pin VFQFPN package constraints for PCB layout. Evaluate the bandwidth adjustability features against specific jitter tolerance requirements of the target network topology.

Part Context

This part belongs to the Renesas 82V3398 series of synchronous Ethernet PLLs. It is distinct from other Renesas timing chips like the 82V3395BNLG8, which may offer different pin counts or feature sets. The 82V3398NLG8 specifically targets WAN synchronization needs, differing from LAN-focused or general-purpose clock generators in its optimized jitter filtering characteristics for long-haul networks.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify direct replacements only through official Renesas obsolescence notices or cross-reference guides.
