| Abstract: | A novel kind of microcomputer compensated crystal oscillator （MCXO） based on C8051F061 is presented. The C8051F061 microcontroller has rich hardware resources and makes full use of software, so the MCXO has many advantages such as simple structure, small size, low power con- sumption and short start preheating time etc. Its composite indicators are. frequency-temperature stability： ±5 × 10^-8 （-40℃-＋85 ℃ ）, size： 35 × 23 × 10mm^3, average power consumption≤60mW. |
