82P33913-1NLG

Overview

The 82P33913-1NLG is a Synchronous Equipment Timing Source (SETS) integrated circuit manufactured by Renesas Electronics. Designed for telecom interface applications, this component functions as a SYNCE 1588 PLL to manage timing references and clock generation for Synchronous Ethernet networks. It complies with ITU-T G.8264 and G.8262 standards for SyncE-based clocks. The device supports Stratum 3 and SONET Minimum Clock requirements, enabling low-jitter clock outputs for Ethernet, SONET/SDH, and PDH interfaces. It features automatic reference selection and configuration loading from external EPROM.

Feature Summary

• Complies with ITU-T G.8262 (EEC), G.813 (SEC), and Telcordia GR-253-CORE (Stratum 3/SMC) standards
• Supports IEEE 1588 based clock generation via DPLL1 configured as a Digitally Controlled Oscillator (DCO)
• Generates low-jitter clocks (<1ps RMS, 12kHz to 20MHz) for Ethernet, SONET/SDH, and PDH interfaces
• Automatically loads configuration from an external EPROM after reset without processor intervention

Applications

• Synchronous Ethernet Equipment Clock (EEC) implementations
• SONET/SDH network timing synchronization
• IEEE 1588 Precision Time Protocol (PTP) master applications
• Network timing sources requiring Stratum 3 compliance

Procurement Notes

Mouser currently does not supply the 82P33913-1NLG in the specified region. The part is listed under restricted supply conditions, indicating it may be available only through limited sales channels or special factory orders. Verification of current availability directly with the manufacturer or authorized distributors is required before design finalization.

Selection Notes

Select the 82P33913-1NLG when designing systems requiring strict adherence to ITU-T G.8262 and G.8264 standards for Synchronous Ethernet. Ensure the design accommodates the VFQFPN-72 package and supports the necessary external components for EPROM configuration and TCXO/OCXO sourcing. Verify that the application requires the specific frequency synthesis capabilities provided by the fractional-N input dividers.

Part Context

This component belongs to the 82P33913 family of Synchronous Equipment Timing Sources. The suffix 'NLG' typically denotes the lead-free RoHS-compliant variant in the VFQFPN-72 package. Related parts in the series include the 82P33913NLG8, which includes software support and utilizes a reel packaging format instead of tray packaging.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Renesas Electronics for migration guides or equivalent products within the 82P33xx series that meet the same ITU-T compliance requirements.
