Single module provides ovened crystal, GPS, time and frequency reference
Packed with the latest integration technology, including the patented SmarTiming+ GPS/GNSS disciplining software operating at 1-nanosecond resolution, the GXClok™-500 reduces the price point for the next generation of high-performance timing applications.
Designed with a highly adaptable architecture, the GXClok-500 features a small footprint of 76 x 20 x 38 mm, 50-channel GPS/GNSS receiver, high frequency accuracy when locked to GPS of ±3E-12, and high frequency stability over a wide temperature range option of ±3E-10 over -40°C to +85°C.
Other chracteristics include low aging of ±1E-10/day, high long-term frequency stability of 2E-8/year, and low phase noise of -95 dBc/Hz at 1 Hz from the 10 MHz carrier. Power consumption is 3 W nominal, short-term stability is 1E-11 at 1 second, and warm up takes 7 minutes.
High holdover options when unlocked to GPS/GNSS of 10 microsecond/24 hours and low g-sensitivity options of 5E-10/g are available.
According to Pascal Rochat, Founder and Managing Director of Spectratime, "Integrating a high precision OCXO crystal oscillator and a flexible GPS/GNSS receiver in a 3.6 inch cube volume makes it an attractive product for many cross industry applications."
