"The SA.45s reportedly provides ... short-term stability (Allan Deviation) of 2E-10 @ 1 sec, long-term aging of 3E-10/month" From the data sheet of the bigger Rubidium micro-clocks: SA.33/35m: 1 Sec stability- <3E-11 1 month aging - +/1 1E-10 Neat, but only really of benefit to *really* space/weight/power critical devices. "The cesium atoms are “excited,” or heated to a vapor state by a beam generated from a vertical-cavity surface emitting laser (VCSEL) that passes between upper and lower polymide heater/suspension strips.
