FTS125-COO-010.0M

Overview

The Connor Winfield FTS125-COO-010.0M is a GPS-disciplined oscillator module based on an OCXO, providing a phase-locked 10 MHz CMOS output and a 1 PPS CMOS signal. It operates on a +3.3V supply (3.135V to 3.465V) with typical currents of 1.2A for the timing circuitry and 1.0A for interfacing. The unit features selectable references including GPS, external 10 MHz, or external 1 PPS, alongside holdover capability. It includes three alarm outputs for Loss-of-Lock, Holdover, and Antenna Fault, and meets ITU-T G.811 and ETSI-PRC wander generation masks.

Feature Summary

• GPS-based phase lock loop generating 10 MHz CMOS and 1 PPS CMOS outputs
• Three selectable reference inputs: GPS, External 10 MHz LVCMOS, or External 1 PPS LVCMOS
• Holdover performance with yearly aging of 80 ppb and temperature stability of ±20 ppb
• Compliance with ITU-T G.811 and ETSI-PRC wander generation masks

Applications

• Telecommunications network synchronization
• Base station timing standards
• Test and measurement equipment requiring high-stability time references

Procurement Notes

Verify that the application supports the high current consumption of up to 1.2A for VCC1 and 1.0A for VCC2. Ensure the power supply provides stable +3.3V within the specified range of 3.135V to 3.465V. Confirm the availability of an outdoor GPS antenna with MCX connector and sufficient gain (minimum 10dB) for optimal receiver performance.

Selection Notes

Select this model for fixed-position applications requiring GPS-derived timing accuracy. The 'COO' suffix indicates an OCXO reference and OCVCXO oscillator type. For mobile applications, contact the manufacturer as standard models are designed for fixed position only. Ensure the environment allows for a full sky view for the GPS antenna.

Part Context

This component belongs to the 125 Series of GPS Disciplined Oscillators from Connor Winfield. It integrates a Wi125 GPS receiver with a low jitter VCXO/OCXO to provide precise frequency and time standards. The module is housed in a 32-pin DIP package measuring 4.15” x 3.3” x 0.718”.
