GF-8804

Overview

The Volgen + Furuno GF-8804 is a multi-GNSS disciplined oscillator (GNSSDO) module designed for high-precision frequency generation. It integrates a GNSS receiver, oven-controlled crystal oscillator (OCXO), low-dropout regulator, and antenna detection circuitry into a single unit. The device supports multiple satellite navigation systems including Galileo, GLONASS, GPS, and QZSS to ensure robust positioning capability. Operating at a nominal frequency of 10 MHz with a supply voltage of 5.5V, it provides stable timing references suitable for critical infrastructure applications requiring long-term frequency stability.

Feature Summary

• Integrates multi-GNSS receiver, OCXO, LDO regulator, and antenna detection in one module
• Supports Galileo, GLONASS, GPS, and QZSS constellations for enhanced availability
• Provides high-stability 10 MHz output via GNSS discipline mechanism

Applications

• Telecommunications base station synchronization
• Power grid timing and protection relays
• Scientific research instrumentation requiring precise frequency standards
• Navigation reference stations

Procurement Notes

Verify the specific hardware revision and firmware version against project requirements before ordering. Confirm that the 5.5V supply voltage aligns with the system power architecture. Ensure the mounting configuration matches the mechanical design constraints. Check for any regional export control classifications or compliance certifications required for the intended deployment environment.

Selection Notes

Select the GF-8804 when a self-contained GNSS-disciplined solution is preferred over separate components. Compare against the GF-8805 if different form factors or voltage levels are needed. Consider environmental operating ranges and physical dimensions relative to the enclosure space. Evaluate the need for integrated antenna detection features versus external monitoring solutions.

Part Context

The GF-8804 belongs to the GF-88 series of multi-GNSS disciplined oscillators manufactured by Volgen + Furuno. This series includes variants such as the GF-8802 and GF-8805, which share similar core functionalities but differ in package size, supply voltage, and mounting style. The GF-8804 specifically utilizes a 5.5V supply and a larger module footprint compared to some other series members.

Replacement Considerations

The GF-8805 serves as a related variant within the same product family, offering similar GNSSDO functionality with potential differences in physical dimensions or electrical specifications.
