QDi.AC
Quantum Diamond Atomic Clock
QDi.AC is a frequency reference based on the magnetic spin transitions of a synthetic crystal diamond. It is a through-hole component intended for soldered integration into system electronics that require a long-holdover clock source. The QDi.AC leverages the inherent stability and ruggedness of a synthetic diamond crystal to enable exceptional holdover in a variety of application areas and environments, while generating a pre-configured 10 or 20 MHz LVCMOS or sine wave reference signal.
