SCOPE

1.1

General. This specification defines the design, assembly and functional evaluation of

high reliability Oven-Controlled Crystal Oscillators (OCXO) produced by Vectron

International. Devices delivered to this specification are processed with standard

documents, procedures, and processes developed by Vectron International. Ordering

information, including an order entry sheet, is detailed to facilitate part number definition

and ordering.

1.2

Classification. All devices defined by this specification are Type 4 or Type 6 oscillators

In Accordance With (IAW) MIL-PRF-55310.

1.2.2

Oscillator Class. The oscillator classes covered by this specification are identified buy

technology class as follows:

Class 1 --- Oscillators using discrete technology. This technology uses exclusively discrete

type electronic parts (including surface mount devices) assembled and

interconnected on a printed circuit board or an insulating substrate.

Class 2 --- Oscillators using microelectronic (hybrid) technology. This technology uses

microelectronic circuit elements electrically and mechanically interconnected on

an insulating substrate upon which resistors, capacitors, or conductors have

been deposited, and used in a package that will be backfilled with an inert gas.

Class 3 --- Oscillators using mixed technology (i.e., a combination of discrete technology

and microelectronic technology).

1.2.3

Radiation Environment. The radiation environment is identified by a single letter as follows:

R --- Radiation Environment, Swept High Q Synthetic Quartz

X --- Non-Radiation Environment, High Q Synthetic Quartz
