CTS Reeves model 105 is a high stability
OCXO housed in a Standard TCXO package.
At only .53 high it is ideal for applications
requiring high stability in small size such as
rack mounted or portable applications. The
105 has Sinewave output for more design
flexibility. Also there are a variety of tempera-
ture and stability options to choose from.
