82V3358TFG

Overview

The Renesas 82V3358TFG is a Synchronous Ethernet WAN Phase-Locked Loop (PLL) designed to provide node clocks compliant with ITU-T G.8261 and G.8262 standards. It exceeds GR-253-CORE jitter generation requirements for OC-12 and ITU-T G.813 for STM-16. The device integrates T0 and T4 Digital Phase-Locked Loops (DPLLs), employing both DPLL and Analog PLL (APLL) technologies to minimize external components while ensuring excellent jitter performance. It supports programmable bandwidth from 0.1 Hz to 560 Hz and offers holdover accuracy of 1.1x10^-5 ppm absolute.

Feature Summary

• Provides node clocks for ITU-T G.8261/G.8262 Synchronous Ethernet networks
• Integrates T0 and T4 DPLLs with independent or locked locking modes
• Supports programmable DPLL bandwidth (0.1 Hz to 560 Hz) and damping factor
• Exceeds GR-253-CORE (OC-12) and ITU-T G.813 (STM-16) jitter generation requirements

Applications

• Synchronous Equipment Timing Source including Stratum 3, SMC, 4E, and 4 clocks
• Cellular and WLL base-station timing for GSM and 3G networks
• DSL access concentrators (DSLAM) and Japan TCM-ISDN network timing
• Synchronous Ethernet WAN nodes requiring high jitter attenuation

Procurement Notes

Verify the specific suffix 'TFG' against the manufacturer's official datasheet to confirm package type and temperature range. Confirm current lifecycle status as this component family may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for the TQFP-64 package if applicable to similar variants.

Selection Notes

Select this component when strict adherence to ITU-T G.8261/G.8262 synchronization standards is required. The integrated T0/T4 DPLL architecture reduces bill-of-materials complexity compared to discrete solutions. Verify that the programmable bandwidth settings meet the specific network jitter and wander filtering requirements of the target application.

Part Context

The 82V3358 belongs to the Renesas 82V33xx series of clock generators and support products. It serves as a specialized solution for telecommunications infrastructure, specifically targeting synchronous Ethernet transport networks. It is functionally related to other WAN PLLs in the portfolio but distinguished by its specific integration of dual DPLLs and compliance with legacy SONET/SDH jitter masks alongside modern SyncE standards.

Replacement Considerations

Public documentation identifies the 82P33714 as a replacement product, described as a Synchronous Equipment Timing Source for Synchronous Ethernet. Verify pinout and register compatibility before substitution.
