GF-8803

Overview

The Volgen + Furuno GF-8803 is a GNSS Disciplined Oscillator (GPSDO) module designed for high-precision timing applications. It integrates an Oven-Controlled Crystal Oscillator (OCXO) with multi-GNSS reception capabilities, supporting Galileo, GLONASS, GPS, and QZSS constellations to ensure robust satellite lock. The device operates on a 3.7V supply voltage and delivers a stable 10 MHz output frequency that remains coherent with the internal 1PPS signal synchronized to UTC. Housed in a through-hole module package measuring 34.00mm x 27.00mm, it functions within a temperature range of -40°C to 85°C. This component provides reliable time-frequency reference performance suitable for demanding environments.

Feature Summary

• Integrates OCXO technology with multi-GNSS receiver for enhanced stability
• Outputs 10 MHz frequency coherent with 1PPS UTC-synchronized signal
• Supports multiple satellite constellations including Galileo, GLONASS, GPS, and QZSS

Applications

• 5G network infrastructure requiring precise time synchronization
• Telecommunications base stations needing stable frequency references
• Scientific instrumentation requiring UTC-traceable timing signals

Procurement Notes

Verify the specific hardware specifications against the official GF-880x Series User Guide and Hardware Specs datasheets prior to integration. Confirm that the 3.7V supply requirement aligns with your system power architecture. Ensure the through-hole mounting style fits your PCB layout constraints. Check current availability status as lead times may vary due to manufacturing schedules.

Selection Notes

Select the GF-8803 when a compact, self-contained timing solution is required that combines oscillator stability with autonomous GNSS locking. Compare against the GF-8802 and GF-8805 if different form factors or voltage levels are needed. Consider the GF-8804 evaluation kit if initial development testing of the underlying navigation engine is necessary before finalizing the oscillator module design.

Part Context

The GF-8803 belongs to the GF-880X series of GNSS disciplined oscillators manufactured by Volgen + Furuno. This series includes variants such as the GF-8802, GF-8804, and GF-8805, which share similar functional principles but differ in physical dimensions, mounting styles, and operating voltages. The GF-8803 specifically utilizes a smaller through-hole module format compared to the larger base-mounted GF-8805.

Replacement Considerations

The GF-8802 serves as a direct alternative within the same series, offering similar functionality in a slightly different package size. The GF-8804 is available as an evaluation kit version for testing purposes. No other cross-model substitutes are officially documented.
