The Low Noise Chip Scale Atomic Clock LN CSAC combines the accuracy of an atomic clock with the spectral purity of an ovenized crystal oscillator in a compact size requiring low input power.
the developer of the CSAC, has incorporated a low power OCXO within the frequency control loop of the atomic clock enabling exceptional performance for both Allan Deviation and Phase Noise. This level of performance cannot be achieved using external phase locked loops.

The LN CSAC provides a 10 MHz sine wave output and 1 PPS output, with short-term stability [Allan Deviation] of TAU = 1 sec, aging of and maximum frequency change of ±5E-10 over an operating temperature range of to +35°C.

The LN 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 LN 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 RS-232 serial interface is built in to the LN CSAC. 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 LN CSAC’s internal time-of-day clock.

The LN CSAC acts as a frequency and timing subsystem while requiring limited size, weight and power.

Microsemi invented portable atomic timekeeping with QUANTUM , the first family of miniature and chip scale atomic clocks.

Choose QUANTUM class for best-in-class stability, size, weight and power consumption.
