GRClok-1500 Image

The GRClok-1500 from Safran is a smart, low cost, compact rubidium oscillator with an optional integrated GPS / GNSS receiver. This 10 MHz Rubidium oscillator is based on the patented, adaptive SmarTiming+ technology – that disciplines the GPS/GNSS reference at 1 ns resolution - providing a host of complex time & frequency features in a single package solution to achieve state-of-the-art performance, reliability and extended lifetime. It delivers a sine wave output with a phase noise of -145 dBc/Hz at 1 kHz offset. It has harmonics of less than -40 dBc and spurious levels of below -80 dBc.

The optional GPS/GNSS receiver is u-Blox's advanced 50-channel LEA-6T GPS receiver with a 6-position engine and anti-jamming technology. It supports multi-navigational satellite system receivers, including GPS, Galileo, GLONASS, IRNSS, and BDS/COMPASS.

The GRClok-1500 is available in a module that measures 128.0 x 95.0 x 38.1 mm with SMA connectors. It requires a DC supply of 12/24 V and has an RS232 standard interface for control & monitoring commands. The oscillator is ideal for applications in mobile & wired telecom/datacom infrastructure, military communications & surveillance systems, high precision instruments, time & frequency systems, financial trading systems, big data timing systems, and navigational & positioning systems. The oscillator is compatible to the Stanford PRS10 model and fits in a compact 1U chassis.
