Connor-Winfield Launches Innovative GPS Receiver and Oscillator Module
Date: March 11, 2025
The CW25-GDO-DK series by Connor-Winfield Corp., based in Aurora, Illinois, has just been unveiled as a powerful solution for time and frequency synchronization. This combined module incorporates both a GPS receiver and a GPS disciplined oscillator, aimed at enhancing synchronization capabilities in various applications.
Equipped with a Global Positioning System (GPS) receiver, the module utilizes a digital phase-locked loop circuit to regulate the 1PPS (Pulse Per Second) signal derived from GPS reception. This system features autonomous phase calibration, effectively mitigating sawtooth errors and preventing conditions known as hanging bridges.
Besides producing a phase-aligned 1PPS output, the module delivers three clock signals aligned to the same. Among these outputs, one is a digitally synthesized clock that can vary in frequency from 150 Hz to 80 MHz, alongside two low jitter 10 MHz clock outputs. These outputs are generated from an integrated APLL block and offer options for both 3.3-volt CMOS and differential LVPECL/LVDS signals, with frequency capabilities reaching up to 700 MHz.
High-Performance Clock Signals
The CW25-GDO-DK features an on-board TCXO (Temperature Compensated Crystal Oscillator) which serves as the system’s master clock, ensuring solid holdover performance. Additionally, the module accommodates optional external inputs for both 1PPS and 10 MHz clock, further bolstering its holdover capabilities.
This time and frequency synchronization product is ideal for applications such as wireless systems, software-defined radio systems, time stamping, IEEE 1588v2, and scenarios requiring precision long-term time and frequency generation using a 1PPS frequency source.
