OCXO Opens Way For Medical Designs

Jan. 11, 2011

Model NV47AE is an oven-controlled crystal oscillator (OCXO) from Bliley Technologies which is actually well suited not only to medical applications, but for military and telecommunications uses as well. It is specifically designed where high stability is needed in tight spaces. Available with frequencies from 5 to 13 MHz, it is 1 in. or less in height but boasts +/- 0.5 ppb minimum stability. The phase-noise performance can be specified as one of three options: A, B, and C. Option A includes phase noise of -80 dBc/Hz offset 1 Hz from the carrier, -150 dBc/Hz offset 1 kHz from the carrier, and -155 dBc/Hz offset 10 kHz from the carrier. Option B provides phase noise of -90 dBc/Hz offset 1 Hz from the carrier, -155 dBc/Hz offset 1 kHz from the carrier, and -160 dBc/Hz offset 10 kHz from the carrier. Option C offers phase noise of -95 dBc/Hz offset 1 Hz from the carrier, -160 dBc/Hz offset 1 kHz from the carrier, and -165 dBc/Hz offset 10 kHz from the carrier. The stable reference oscillator is well suited for base stations, test equipment, synthesizers, and digital switching applications.
