Description
The Model 122 series combines the advantage of the double-oven and internal heated resonator (IHR)
technologies providing less than 1W power consumption at as high as 0.2ppb temperature stability and
0.2ppb/day aging (for 10MHz frequency) in a 20 x 20 mm package. The Model 122 oscillators are excellent to
use in high-end clock systems, instrumentation, and other applications where ultra high stability and miniature
size are required.
