82P33714ANLG

Overview

The Renesas 82P33714ANLG is a Synchronous Equipment Timing Source (SETS) designed for Synchronous Ethernet applications. It complies with ITU-T G.8262 for Ethernet Equipment Clocks (EEC), ITU-T G.813 for Synchronous Equipment Clocks (SEC), and Telcordia GR-253-CORE for Stratum 3 and SONET Minimum Clock (SMC). The device employs Digital Phase-Locked Loops (DPLL) and Analog Phase-Locked Loops (APLL) to provide excellent jitter performance while minimizing external components. It supports programmable DPLL bandwidth from 0.1 Hz to 560 Hz in 11 steps and damping factors from 1.2 to 20 in 5 steps. The component integrates T0 and T4 DPLLs, offering holdover accuracy of 1.1x10^-5 ppm absolute and 4.4x10^-8 ppm instantaneous.

Feature Summary

• Complies with ITU-T G.8262, G.813, and GR-253-CORE standards for SyncE and SONET/SDH timing.
• Integrates T0 and T4 DPLLs with automatic reference selection state machines and hitless switching capabilities.
• Supports fractional-N input dividers for diverse reference frequencies including 10G Ethernet, OTN, SONET/SDH, and GNSS.
• Provides low-jitter output clocks (<1ps RMS between 12kHz and 20MHz) suitable for direct Ethernet interface synchronization.

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 utilizing 1 PPS references from GPS/GNSS sources.

Procurement Notes

The 82P33714ANLG is designated as not recommended for new designs. Availability may be limited or restricted to factory special orders. Verify current stock status and lead times with authorized distributors, as the component may be subject to end-of-life transitions. Ensure compatibility with existing system requirements before procurement.

Selection Notes

Select this component for applications requiring strict adherence to ITU-T G.8262 and G.813 standards. It is suitable for systems needing integrated clock management with minimal external passive components. Consider the 72-pin QFN package constraints and moisture sensitivity level when designing the PCB layout. Verify that the supported input reference frequencies align with the specific network infrastructure being deployed.

Part Context

The 82P33714 series serves as a comprehensive solution for synchronous equipment timing in telecommunications infrastructure. It consolidates multiple clock generation and management functions into a single chip, reducing board space and complexity. The ANLG suffix typically denotes the lead-free and RoHS-compliant variant of the standard 82P33714 part number within the Renesas portfolio.

Replacement Considerations

As the part is not recommended for new designs, evaluate alternative Renesas timing solutions such as the 82P33914 series for updated feature sets. Cross-reference pinouts and electrical specifications carefully if substituting with other models in the 82P33xxx family to ensure functional compatibility.
