GF-8703

Overview

The GF-8703 is a GNSS Disciplined Oscillator (GPSDO) module manufactured by Volgen + Furuno. It functions as an RF oscillator utilizing Global Navigation Satellite Systems including Galileo, GLONASS, GPS, and QZSS for frequency stabilization. The component operates within a temperature range of -40°C to 85°C and complies with RoHS3 standards. It is classified under RF Misc ICs and Modules.

Feature Summary

• Provides precise frequency discipline using multi-GNSS satellite signals
• Supports multiple global navigation systems including Galileo, GLONASS, GPS, and QZSS
• Designed for high reliability in demanding environmental conditions

Applications

• Navigation system timing references
• Telecommunications base station synchronization
• Test and measurement equipment calibration

Procurement Notes

Verify the current manufacturing status as the GF-8703 may be obsolete or discontinued. Confirm compatibility with existing evaluation kits such as the VF-03 if used in development environments. Check for manufacturer-recommended replacements like the GF-8805 series if availability is restricted. Ensure compliance with export control classifications such as ECCN EAR99.

Selection Notes

Select this module when multi-constellation support is required for robust signal acquisition. Consider the operating temperature range of -40°C to 85°C for industrial applications. Evaluate integration with compatible evaluation hardware like the VF-03 kit for initial testing and validation phases before full deployment.

Part Context

The GF-8703 belongs to the Furuno Multi-GNSS Disciplined Oscillator family. It is often associated with evaluation kits like the VF-03. This series provides stable reference frequencies for critical infrastructure. The component supports various GNSS constellations to ensure continuous operation.

Replacement Considerations

The GF-8805 is a manufacturer-recommended alternative within the same product line. It offers similar disciplined oscillator functionality with updated specifications. Verify pinout and interface compatibility when transitioning from the GF-8703 to newer models.
