82V3202NLG8

Overview

The 82V3202NLG8 is a Synchronous Ethernet WAN PLL manufactured by Renesas Electronics. It operates within a temperature range of -40°C to +85°C and utilizes Silicon technology. The device features two circuits and supports input levels including LVCMOS, LVDS, and LVPECL. It functions at a maximum input frequency of 156.25 MHz with an output frequency range up to 644.5312 MHz. Powered by a 3.3 V supply, it is housed in a QFN-72 package suitable for SMD/SMT installation.

Feature Summary

• Integrates DPLL and APLL technologies to deliver excellent jitter performance while minimizing the requirement for external components.
• Supports Forced or Automatic operating mode switching controlled by an internal state machine across Free-Run, Locked, and Holdover modes.
• Provides programmable DPLL bandwidth and damping factor settings to optimize synchronization characteristics.

Applications

• Synchronous Ethernet node clock generation compliant with ITU-T G.8261/G.8262 standards
• Cellular and WLL base-station timing for GSM and 3G networks
• DSL access concentrator (DSLAM) synchronization

Procurement Notes

Verify component authenticity through authorized channels as counterfeit risks exist. Confirm RoHS compliance status via official documentation before integration. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Validate package integrity upon receipt to prevent soldering defects in the QFN-72 form factor.

Selection Notes

Select this component for applications requiring precise synchronous Ethernet timing solutions. Evaluate thermal management requirements against the specified operating temperature limits. Consider interface compatibility with LVCMOS, LVDS, or LVPECL signals. Assess board space constraints relative to the QFN-72 package dimensions.
