Abstract
PURPOSE:To constitute a small sized and inexpensive highly stable synchronizing oscillator by providing an intermittent timer and a control voltage holding circuit of a voltage controlled crystal oscillator to a PLL circuit of a synchronizing oscillator. CONSTITUTION:A subcarrier from input terminals 1, 2 is amplified by amplifiers 3, 4 and inputted to a balance mixer 5. The output of the balance mixer 5 is given to a distributer 6, a high pass filter 7 and a low pass filter 8 and the result is inputted to a PLL circuit 18 through the switch 15. The PLL circuit 18 has the intermission timer 25 and a control voltage holding circuit 24 of a voltage controlled oscillator 20 to generate a stable output frequency.
