Title:
HIGHLY STABLE FREQUENCY GENERATOR
Document Type and Number:
Japanese Patent JPH08265043
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a frequency generation device which can be used for a part of a digital system used in a radio communication call system such as a clock for a call device, which can stand a long use with less influence by the temperature. SOLUTION: The frequency generation device G is provided with an oscillator 10 for first frequency F1 generation, a reference frequency generation device BT, a feedback means supplying the first number nT of a pulse from the oscillator 10 to a comparison means 13, a means supplying the reference number NT of the pulse to the comparison means 13, means 13, 15 and 16 supplying a correction signal SC as the function of difference Δ between the first number nT and the reference number NT and a means which is the correction circuit 17 of the oscillation frequency F1 of the first oscillator 10 and which is controlled by the signal SC.
