Abstract:
1. A method for providing a frequency output via a Chip Scale Atomic Clock (CSAC)-enabled Time and Frequency Standard (CTFS) architecture, the method comprising: providing an output frequency signal from a Stress Compensated (SC) oscillator to both a first NOT gate and to a microcontroller; providing an output frequency signal from a Voltage Controlled Crystal Oscillator (VCXO) to a second NOT gate; receiving the SC oscillator output frequency signal at the first NOT gate and, based upon the received SC oscillator output frequency signal, providing an output from the first NOT gate to a mixer; receiving the VCXO oscillator output frequency signal at the second NOT gate and, based upon the received VCXO oscillator output frequency signal, providing an output from the second NOT gate to the mixer; and receiving the first NOT gate output and the second NOT gate output at the mixer and, based upon the received first NOT gate output and the received second NOT gate output, providing a mixer output to the microcontroller.
