Description
The model EX-380 Series is a low profile DIP or SMD, Evacuated
Miniature Oven Controlled Crystal Oscillator (EMXO),
available in frequencies from 10 MHz to 80 MHz.
Notes: 1. We acknowledge the support
of the U.S. Army for work on resonators
associated with this product under
contract #1 X66001 - 97-C-8635.
*U.S. Patent 5,917,272.
The EX-380 Series provides exceptionally low aging rates and high
temperature stabilities in an extremely small package over a
wide range of environmental conditions. The through hole
unit measures only 20.8mm x 13.2mm x 7.6mm (0.82" x
0.52" x 0.30"), @ 10 MHz provides aging rates of <1x109/day average, <1x10-7 for the first year and <1x10-6 for 10
years with temperature stabilities to ±1x10-7 over -40°C to
+85°C. Wider temperature ranges are available from -55°C to
+85°C. This is achieved by the application of new resonator
design concepts and technological breakthroughs. This
series of EMXO's bridges the gap between current large,
high precision OCXO's and smaller TCXO'S. The EX-380
Series becomes the most economical choice where there is
a need for spectral purity, short and long term stability, along
with small size and dramatically reduced power consumption.
Standard supply voltages for the EX-380 series are 3.3 Vdc and 5Vdc,
with HCMOS or Sinewave output options. A surface mount
version of this oscillator is available (EX-381/5). Sinewave
output is only available in the surface mount, EX-381, version.

Temperature ( º C)
Recommended Reflow Profile
pre-heating
60 to 90 sec.
@ 140ºC to 160ºC
reflow
40 to 60 sec.
@ >183ºC
Note: EMXO's are precision subsystems with tolerances measured to ±0.001 ppm. The EX-381/5
series has been designed for pick and place reflow soldering. The suggested reflow profile is
shown above. The EX-381/5 may be reflowed one time in the non-inverted state. VI recommends
waiting at least two hours after reflow before measuring the unit.
Handling Precautions
Although protection circuitry has been designed into
this device, proper precautions should be taken to
avoid exposure to electrostatic discharge (ESD) during handling and mounting. VI employs a human-body
model (HBM) and a charged-device model (CDM) for
ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the
circuit parameters used to define the mode. Although
no industry-wide standard has been adopted for the
CDM, a standard HBM (resistance = 1500 ohms,
capacitance = 100pf) is widely used and therefore can
be used for comparison purposes. The HBM ESD
threshold presented here was obtained by using these
circuit parameters.
