CW25-TIM GPS Receiver and Oscillator Module

Connor-Winfield CW25-TIM is a GPS receiver and GPS-disciplined oscillator module combined. Designed specifically for time and frequency synchronization applications. This module incorporates a GPS receiver and a digital PLL circuit for disciplining the 1 PPS signal derived from the receiver’s GPS solution. Autonomous phase calibration capability offsets sawtooth error, eliminating hanging bridge conditions.

In addition to generating a phase-aligned 1 PPS output, the module generates one additional clock signal phase aligned to the 1 PPS signal. This additional LVCMOS output is digitally synthesized to any frequency between 150 Hz and 80 MHz.

An on-board TCXO provides the system’s primary clock for holdover performance. The module supports an optional external 1 PPS input as well as an optional external 10 MHz clock input that can be used for improving holdover performance. This product can be used to generate a high-stability frequency reference for use in wireless systems, software-defined radio systems, time stamping, IEEE 1588v2, and applications employing a 1 PPS frequency source for high-precision, long-term time and frequency generation.
