Vectron International has announced the introduction of its Evacuated Miniature Crystal Oscillator (EMXO). The EX-380/385 series, low profile 4 Pin DIP EMXO is available at selected frequencies from 10 MHz to 80 MHz. The oscillators provide exceptionally low aging rates and high temperature stabilities in a small package over a wide range of environmental conditions. The through hole unit measures 20.8 × 13.2 × 7.6 mm (0.82 × 0.52 × 0.30 inches), provides aging rates of <1 × 10ץ
/day average, <1 × 10ף
for the first year and <1 × 10ע
for 10 years with temperature stabilites to ± 1 × 10 7
over 40°C to +85°C. Wider temperature ranges are available from 㫏 °C to +85°C.
Standard supply voltages for the EX-380 series are 3.3 V DC and 5 V DC, with 12 V DC also available, all with an HCMOS output. A surface mount version of the oscillator is available (EX-385). Sinewave output of +3.0 dBm/50 ohm is available in the surface mount version.
