Quantum SA.45s CSAC Chip Scale Atomic Clock DATASHEET Key Features • Power consumption <120 mW • Less than 17 cc volume, x • 10 MHz CMOS-compatible output • 1 PPS output and 1 PPS input for synchronization • RS-232 interface for monitoring and control • Short term stability Allan Deviation of TAU =1 sec Applications* • Underwater sensor systems • GPS receivers • Backpack radios • Anti-IED jamming systems • Autonomous sensor networks • Unmanned vehicles *The Chip Scale Atomic Clock is not tested, qualified, and rated for space applications. With an extremely low power consumption of <120 mW and a volume of <17 cc, the SA.45s Chip Scale Atomic Clock CSAC brings the accuracy and stability of an atomic clock to portable applications for the first time. The SA.45s provides 10 MHz and 1 PPS outputs at standard CMOS levels, with short-term stability Allan Deviation of 2.5E-10 TAU =1 sec, long-term aging of <9E-10/month, and maximum frequency change of 5E-10 over an operating temperature range of -10°C to +35°C. The SA.45s CSAC accepts a 1 PPS input that may be used to synchronize the unit’s 1 PPS output to an external reference clock with ±100 ns accuracy. The CSAC can also use the 1 PPS input to discipline its phase and frequency to within 1 ns and 1.0E-12, respectively. A standard CMOS-level RS-232 serial interface is built in to the SA.45s. This is used to control and calibrate the unit and also to provide a comprehensive set of status monitors. The interface is also used to set and read the CSAC’s internal timeof-day clock.
