The AXIOM75ULN from AXTAL is an Oven Controlled Crystal Oscillator (OCXO) that operates from 80 to 130 MHz. It provides a Sinewave output waveform with a phase noise of -137 dBc/Hz (at 100 Hz offset) and has spurious levels of -90 dBc. This OCXO has a frequency stability of ±25 ppb and a g-sensitivity of 1.0 ppb/g. It requires a DC supply of 12.0 V and consumes less than 150 mA of current. This oscillator exhibits very low phase noise and has undergone military-standard test procedures to ensure reliability. It is available in a surface-mount package that measures 25.8 x 25.8 x 12.7 mm.
