Chip-scale atomic frequency references
WebThe Microsemi LN-CSAC acts as a frequency and timing subsystem, while requiring limited size, weight, and power. It accepts a 1PPS input that may be used to synchronize the unit's 1PPS output to an external reference clock within ±100 ns accuracy or discipline its phase and frequency to within 1 ns and 1.0 × 10–12, respectively.
