82P33714ANLG8

Overview

The 82P33714ANLG8 is a Synchronous Equipment Timing Source (SETS) for Synchronous Ethernet, compliant with ITU-T G.8262 and G.813 standards. It employs DPLL and APLL technologies to provide node clocks for SyncE, cellular base stations, and DSLAMs. The device supports Stratum 3, SMC, 4E, and 4 clock levels with jitter generation below 1ps RMS (12kHz to 20MHz). It features programmable bandwidth from 0.1 Hz to 560 Hz and holdover accuracy of 1.1x10^-5 ppm absolute. The component integrates T0 and T4 DPLLs, supports automatic hitless switching, and accepts various reference inputs including Ethernet, SONET/SDH, and GNSS.

Feature Summary

• Complies with ITU-T G.8262 (EEC), G.813 (SEC), and Telcordia GR-253-CORE (Stratum 3/SMC)
• Generates low-jitter clocks (<1ps RMS) for Ethernet, SONET/SDH, and PDH interfaces
• Integrates T0 and T4 DPLLs with programmable bandwidth (0.1 Hz to 560 Hz) and damping factor
• Supports automatic hitless input clock switching and phase absorption for large phase-time changes

Applications

• Synchronous Ethernet network nodes requiring EEC or SEC compliance
• Cellular and WLL base stations for GSM and 3G networks
• DSL access concentrators (DSLAM) and Japan TCM-ISDN network timing
• Network timing master applications using 1 PPS references from GPS/GNSS

Procurement Notes

Verify the specific suffix 'ANLG8' against official Renesas documentation to confirm package type and tape-and-reel configuration. Confirm current production status as the base model 82P33714 is marked Not Recommended for New Designs. Ensure compatibility with required external EPROM for boot configuration if processor intervention is not available during startup.

Selection Notes

Select this component when strict adherence to ITU-T G.8262/G.813 jitter masks is required for SyncE infrastructure. The integrated DPLL architecture minimizes external components compared to discrete solutions. Verify that the supported input frequencies (10/100/1000/10G Ethernet, OTN, SONET/SDH) match the system's reference sources. Consider the 72-pin QFN package constraints for PCB layout and thermal management.

Part Context

The 82P33714 belongs to Renesas' Synchronous Equipment Timing Source family designed for high-performance network synchronization. It serves as a central timing hub for managing multiple reference sources and generating precise output clocks for various communication interfaces. The device simplifies design by integrating complex PLL functions and state machines for reference selection into a single chip.

Replacement Considerations

The base part 82P33714 is listed as Not Recommended for New Designs. Consult Renesas for current recommended alternatives within the SETS portfolio. Verify pinout and register compatibility if substituting with newer generations of synchronous Ethernet timing controllers.
