STRUCTURE OF STABLE PIEZOELECTRIC OSCILLATOR

摘要

PROBLEM TO BE SOLVED: To obtain a means for reducing current consumption by improving the frequency temperature characteristic of a stable crystal oscillator. SOLUTION: In a stable piezoelectric oscillator provided with an oscillation circuit and a heater control circuit on a first printed board and provided with thermostats 7 housing a crystal resonator on a second printed board, plural resin supports for connecting the first printed board and the second printed board are used between both of them.
