Quantum SA.45s CSAC

Chip Scale Atomic Clock

Microsemi invented portable atomic timekeeping with QUANTUMTM, the world’s
first family of miniature and chip scale atomic clocks.

Choose QUANTUMTM class for best-inclass stability, size, weight, and power
consumption.

With an extremely low power consumption of <120 mW and a volume of <17 cc, the Microsemi 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 TAU = 1 sec, typical long-term aging of and maximum frequency change of over an operating temperature range of °C to 70 °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. It also use the 1 PPS input to discipline its phase and frequency to within 1 ns and 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 time-of-day clock.
