82V3002APVG

Overview

The 82V3002APVG is a Stratum clock and frequency generator integrated circuit manufactured by Renesas Electronics. It operates as a WAN PLL with dual reference inputs, utilizing an internal Digital Phase-Locked Loop (DPLL) to generate ST-BUS signals. The device supports a maximum frequency of 32.768MHz with one output channel. It accepts CMOS or TTL input levels and features a 2:14 input-to-output ratio. Power supply voltage ranges from 3V to 3.6V. The component is designed for surface mount installation in a 56-SSOP package, measuring 18.4 x 7.5 x 2.3 mm. Operating temperature spans from -40°C to +85°C.

Feature Summary

• Integrates a Digital Phase-Locked Loop (DPLL) for precise signal generation
• Supports dual reference inputs for enhanced synchronization reliability
• Generates ST-BUS compliant outputs for telecommunications applications

Applications

• T1/E1 network synchronization
• OC-3 WAN clock recovery
• PDH and SONET/SDH timing systems

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current product naming conventions to ensure compatibility with latest revisions. Confirm that the 56-SSOP package dimensions align with PCB footprint requirements. Check RoHS compliance status and humidity sensitivity classification prior to assembly. Ensure input voltage levels match the specified CMOS/TTL thresholds for proper operation within the defined temperature range.

Selection Notes

Select this component when dual reference input capability is required for high-reliability WAN synchronization. The integrated DPLL architecture simplifies design compared to discrete solutions. Consider the 32.768MHz frequency limit and single output configuration against system bandwidth needs. Evaluate the 56-SSOP package size constraints relative to available board space and thermal management requirements for the target operating environment.

Part Context

This part belongs to the IDT/Renesas 82V3xxx series of WAN PLLs, designed for telecom infrastructure. It replaces older generations of standalone clock generators by integrating DPLL functionality. The series supports various SONET/SDH and PDH standards. The 82V3002A variant specifically targets T1/E1 and OC-3 applications requiring stable frequency synthesis from multiple reference sources.

Replacement Considerations

The IDT82V3002A is the base model designation. Verify pinout and electrical specifications against any updated datasheets before substitution. No direct cross-manufacturer equivalents are confirmed in public documentation.
