Model 144
OCXO - Ultra Miniature, Ultra Low Power
DIL-14
Features
8MHz to 120MHz frequency range
Industry’s smallest OCXO, 8 mm height
Very short - warm-up time (to 30 sec)
Eco-friendly < 150mW power consumption
HCMOS output
RoHS Status
Applications

Description
The
Model 144
uses the internal heating resonator (IHR) technology with arrangement of the whole oven control
system together with the crystal plate inside the TO-8 vacuum holder to radically reduce the OCXO size, power
consumption, and its warm-up time. In addition, the
Model 144
offers excellent temperature stability, low phase-
noise and aging rate despite its miniature size and extremely low power consumption. The oscillator has the
performance of high-end OCXOs which use conventional oven designs.
