Title: Phase locked loop circuit
Inventor: KAWAHARA NOBUHIRO
IPC: H03L7/187
Filed: 1987-12-28
Abstract: PURPOSE:To establish phase locking in a short time by outputting a reset signal to an integration means and a frequency division means when a digital numeric value from a digitization means comes off a prescribed range. CONSTITUTION:For example, when hit is generated by switching a channel, the digital numeric value (b) changes remarkably, and comes off the prescribed range, therefore, a count detection circuit 17 outputs a reset pulse (c). Then, an integration circuit 13 is reset, and a frequency division circuit 16 starts frequency division from an initial state. Therefore, a control voltage (d) goes to zero, and the frequency of a clock ck output from an oscillator 15 is returned to a central frequency within a control range, and also, the frequency division circuit 16 is returned to the initial state compulsorily, and a pull-in operation is restarted from that state. In such a way, the phase locking can be established in a short time.
