GF-8702

Overview

The GF-8702 is a multi-GNSS disciplined oscillator module manufactured by Volgen + Furuno. It operates at a frequency of 10 MHz and supports multiple satellite navigation systems including GPS, GLONASS, Galileo, and QZSS. The component utilizes an OCXO (Oven-Controlled Crystal Oscillator) architecture to ensure high stability and precision in timing applications. Designed for robust performance, it functions within a temperature range of -40°C to 85°C and requires a supply voltage of 3.7V. The module is housed in a surface-mount package.

Feature Summary

• Integrates multi-GNSS receiver capabilities with OCXO technology for superior frequency stability
• Provides precise 10 MHz timing reference synchronized with global satellite constellations
• Engineered for reliable operation across wide industrial temperature ranges

Applications

• Base station synchronization requiring high-precision timing references
• Telecommunications infrastructure needing stable clock sources
• Scientific instrumentation demanding accurate frequency standards

Procurement Notes

This component has reached end-of-life status and is no longer manufactured by the producer. Sourcing new units directly from the manufacturer is not possible. Procurement efforts should focus on identifying verified surplus stock or authorized distributors holding remaining inventory. Buyers must verify the authenticity and storage history of available units to ensure operational reliability given the discontinued status.

Selection Notes

Designers seeking this specific model must account for its obsolete status when planning long-term production cycles. Alternative solutions within the same product family, such as the GF-8802 series, offer comparable functionality with current manufacturing support. Engineers should evaluate pin compatibility and thermal requirements when transitioning to successor modules to maintain system integrity without extensive redesign.

Part Context

The GF-8702 belongs to the GF-87xx series of GNSS disciplined oscillators produced by Volgen + Furuno. This series integrates multi-GNSS receivers with oven-controlled crystal oscillators to deliver highly stable frequency outputs. These modules are designed to provide precise time and frequency references by locking onto satellite signals, serving as critical components in applications where standard crystal oscillators lack sufficient long-term stability.

Replacement Considerations

The GF-8802 is documented as a direct substitute for the GF-8702. Both components share similar specifications and form factors, facilitating potential migration paths for designs requiring updated supply chain availability while maintaining functional equivalence.
