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 Portable Wireless Communications Portable Wireless Devices Synthesizers Battery Powered 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 phasenoise 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.
