GPS receiver and oscillator module for time and frequency synchronization introduced by Connor-Winfield

AURORA, Ill. – Connor-Winfield Corp. in Aurora, Ill., is introducing the CW25-GDO-DK series combined GPS receiver and GPS disciplined oscillator module for time and frequency synchronization applications.

This GPS receiver and oscillator module incorporates a Global Positioning System (GPS) receiver and a digital phased-locked loop circuit for disciplining the 1PPS signal derived from the receiver's GPS. Autonomous phase calibration capability offsets sawtooth error eliminating hanging bridge conditions.

In addition to generating a phase aligned 1PPS output, the module generates three clock signals phase-aligned to the 1PPS signal. Output clocks include one digitally synthesized clock output at frequencies from 150 Hz to 80 MHz and two low jitter 10 MHz clock outputs generated from an integrated APLL block with options for 3.3-volt CMOS and differential LVPECL/LVDS signals at frequencies to 700 MHz.

Clock signals

An on-board TCXO provides the system's master clock for holdover performance. The module supports an optional external 1PPS input as well as an optional external 10 MHz clock input that can be used for improving holdover performance.

This time and frequency synchronization product can generate a high-stability frequency reference for use in wireless systems, software-defined radio systems, time stamping, IEEE 1588v2, and applications employing a 1PPS frequency source for precise long-term time and frequency generation.
