The CTS Reeves Model 322 is a low cost
VCXO, enclosed in a 14 Pin DIP Package for
use in Phase Lock Loop Applications. It's
small size means more application flexibility.
The Model 322 is available with a variety of
pullability and stability options and is useful
in almost any VCXO application. Low noise
means superior jitter performance in
communication applications.
