the Wi125 GPS timing receiver module from Connor-WinfieldDesigned for use in synchronization and timing in WiMax applications, the Wi125 GPS timing receiver module from Connor-Winfield has an on-board programmable NCO oscillator that outputs a synthesized frequency up to 30 MHz. Steered by a GPS receiver, the self-survey mode of operation allows the receiver to enter a position hold mode, allowing accurate timing to be continued with only one satellite being tracked. Features include a phase alignment of 1 PPS/10 MHz with holdover being based on the local oscillator, dismissing spurious GPS measurements during reacquisition.
