FTS250-010.0M

Overview

The Connor Winfield FTS250-HP-010.0M is a GPS/GNSS-driven mixed-signal phase lock loop module providing precision timing and synchronization. It generates a 10 MHz CMOS output, a 10 MHz sine output (~9 dBm), and a 1 PPS CMOS output from an onboard low jitter VCXO. The unit locks to a 1 PPS reference derived from the integrated LEA-M8F GPS receiver but can also synchronize to external 10 MHz or 1 PPS references via mode control inputs. Operating on a +3.3 V supply with current consumption of 270 mA (VCC1) and 36 mA (VCC2), it features three selectable alarm outputs for Loss-of-Lock, Holdover, and Antenna Fault status.

Feature Summary

• Phase locked 10 MHz CMOS and Sine outputs alongside a 1 PPS CMOS output
• Three selectable reference modes: GPS, External 10 MHz, or External 1 PPS
• Integrated LEA-M8F GPS receiver with SMA bulkhead antenna connection
• Alarm outputs indicating Loss-of-Lock, Holdover, and Antenna Fault conditions

Applications

• Precision timing and synchronization systems
• Time stamping applications requiring high-end cost-sensitive solutions
• Network synchronization compliant with ITU-T G.811 Wander Generation Mask

Procurement Notes

Verify the specific holdover thermal stability option required for the application environment. The model suffix indicates the oscillator type used for holdover performance; standard configurations utilize TCXO options such as T1 (±200ppb at -40°C to 85°C). Confirm that the selected variant matches the necessary frequency stability specifications before procurement.

Selection Notes

Select the appropriate holdover specification based on operating temperature requirements. Options include TCXO variants like T1 (-40°C to 85°C, ±200ppb) or T2 (0°C to 70°C, ±100ppb), and OCXO variants like O1 (±10ppb) or O2 (±20ppb). Ensure the design accommodates the physical dimensions of the 28-pin DIP module and provides adequate clearance for the SMA antenna connector.

Part Context

This component belongs to the FTS250-HP Series of GPS Disciplined Oscillators designed for fixed position operation. The series combines a phase lock loop circuitry with a GNSS receiver to provide superior timing solutions. The datasheet SG176 details the electrical characteristics and pinout for this specific 10 MHz output configuration.

Replacement Considerations

Direct replacement requires matching the 28-DIP package and pinout compatibility. Alternative models within the FTS250-HP series offer different holdover stabilities (e.g., OCXO vs. TCXO) which may affect power consumption and size. Verify that any substitute maintains the required ITU-T G.811 compliance and reference input/output logic levels.
