The FEI Series FE103A features operation from 5
MHz to 20 MHz with low phase noise and excellent stability.
Typical phase noise is 142 dBc at 10 Hz from the
carrier, 148 dBc at 100 Hz from the carrier, 155 dBc at 1 kHz
from the carrier and 158 dBc at 10kHz and at 100 kHz from the carrier.
This oscillator is a double oven design using a 5th
overtone SC cut crystal to insure both excellent long term stability
and temperature stability.
Aging is 3x107/Year
and 1x106 /10 years. Temperature
stability is 1x1010 over 10°
to 60°C.
The FE103A was designed for applications such as
reference for Communications Systems and wireless applications such
as cellular phone base stations.
