Production Engineering Measure for Temperature Compensated Microcircuit Crystal Oscillator.

摘要

The objective of this program is to establish a production capability for a microcircuit temperature compensated oscillator (MCTCXO) suitable for use as the reference oscillator in advanced FM communications equipment. Primary characteristics of the MCTCXO are small size,low power consumption,high reliability and frequency-temperature stability of +or -0.0000025over the range of -40C to +80C. The contract will be accomplished in two steps. Step I will encompass the MCTCXO design,development engineering and fabrication of the tooling and production equipment necessary to obtain first article approval. A pilot run of 440units (110each of four frequencies) will be accomplished to verify production procedures,tooling and methods. The work in Step II will consist of all production planning necessary to expand the production rate to 100units per eight hour shift on a mass production basis short of any procurements or actual manufacturing. The first quarterly report described the basic concept to be used in developing the MCTCXO as well as some circuit analysis. This report discusses the selection of the custom CMOS chip which will use silicon-on-sapphire technology in it's construction. Final CMOS specifications as well as specifications for the hybrid circuitry are included. (Author)
