OCXO Cuts Noise To 40 MHz

Model OX-501 is a surface-mount oven-controlled crystal oscillator (OCXO) that is ideal for cellular base stations and military communications equipment, as well as in test equipment. It is supplied in a 6-pin surface-mount package and available in frequencies from 10 to 40 MHz, with standard frequencies of 10, 12.8, 19.2, 20, and 38.88 MHz. Model OX-501 can be furnished with stabilities of 20 PPB or 100 PPM from -20 to +70C or from -40 to +85C. The initial frequency tolerance is 0.5 PPM, with variations of 20 PPB with changes in supply voltage (within 5%), and 30 PPB with changes in load (within 5%). After 30 days of operation, the aging rate is 5 PPM per day. The typical warmup time is 3 minutes. The OCXO consumes 0.5 W typical power at +3.3 VDC under steady-state operation. The phase noise for a supply of +1.4 VDC is -60 dBc/Hz offset 1 Hz from the carrier, -100 dBc/Hz offset 10 Hz from the carrier, -128 dBc/Hz offset 100 Hz from the carrier, -140 dBc/Hz offset 1 kHz from the carrier, and -148 dBc/Hz offset 10 kHz from the carrier.
