FTS375-010.0M

Overview

The Connor Winfield FTS375-010.0M is a GPS Disciplined Oscillator (GPSDO) module providing precision timing and synchronization. It generates a 10 MHz CMOS output, a 10 MHz SINE output, and a 1 PPS CMOS output from an onboard low jitter OCXO. The module locks to GPS signals or external references via mode control inputs. Operating on a +3.3V supply within a 36-pin DIP package, it includes alarm outputs for Loss-of-Lock, Holdover, and Antenna Fault.

Feature Summary

• Phase locked 10 MHz CMOS and SINE outputs with <1 ps RMS phase noise
• Three selectable reference modes: GPS, External 10 MHz, or External 1 PPS
• Integrated holdover capability using onboard OCXO
• Alarm status outputs for Loss-of-Lock, Holdover, and Antenna Fault

Applications

• Precision timing and synchronization systems
• Telecommunications network synchronization
• Test and measurement equipment requiring stable frequency references

Procurement Notes

Verify the specific ordering suffix matches the required output frequency configuration. Confirm that the application environment supports the fixed-position mechanical design and provides adequate ventilation for the through-hole module. Ensure the external antenna meets the specified gain and current draw requirements for optimal receiver performance.

Selection Notes

Select this module when high stability is required in cost-sensitive applications. The FTS375 requires an outdoor mounted GPS antenna for best performance. Verify that the system can accommodate the 3.937” x 1.969” x 0.708” form factor and the necessary serial I/O connections for NMEA message access and manual mode control.

Part Context

The FTS375 belongs to the 125 Series of GPS Disciplined Oscillators from Connor-Winfield. This series combines GPS timing receivers with high-quality oscillators to provide superior timing solutions. The module utilizes a mixed-signal phase lock loop architecture to discipline the internal oscillator based on satellite data or external references.

Replacement Considerations
