GF-8802

Overview

The GF-8802 is a GNSS Disciplined Oscillator (GPSDO) manufactured by Volgen + Furuno, designed to provide high-stability frequency references. It integrates an Oven-Controlled Crystal Oscillator (OCXO) disciplined by global navigation satellite systems including Galileo, GLONASS, and GPS. The module operates at a nominal frequency of 10 MHz with a supply voltage of 3.7V. It features a through-hole mounting style within a module package measuring 34.00mm x 27.00mm in footprint and a maximum seated height of 1.40mm. The device supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Integrates OCXO technology with GNSS discipline for enhanced long-term frequency stability
• Supports multiple global satellite constellations including Galileo, GLONASS, and GPS
• Provides a stable 10 MHz reference output signal

Applications

• Telecommunications base station synchronization
• Test and measurement equipment requiring precise time/frequency references
• Navigation system timing applications

Procurement Notes

Verify the specific revision level and hardware specifications against the official GF-880x Hardware Specs document prior to integration. Confirm that the 3.7V supply requirement aligns with the target system design. Ensure mechanical clearance accommodates the module dimensions and through-hole mounting requirements. Check for any recent product change notices affecting pinout or performance characteristics.

Selection Notes

Select the GF-8802 when high stability is required without the complexity of external rubidium or cesium standards. Compare against the GF-8805 if a 5.5V supply and different form factor are preferred. Consider the GF-8801 or GF-8803 if alternative voltage levels or mounting styles better suit the application constraints. Evaluate thermal management needs given the OCXO heating element.

Part Context

The GF-8802 belongs to the GF-880X series of GNSS disciplined oscillators from Volgen + Furuno. This series includes variants such as the GF-8801, GF-8803, and GF-8805, which differ primarily in supply voltage and physical dimensions. The GF-8802 specifically targets applications requiring a compact, low-voltage solution with through-hole compatibility.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacements should be sought within the GF-880X series based on voltage and size requirements.
