Title: Lock-in system
Inventor: KIMURA MASATOSHI
IPC: H04L7/033
Filed: 1982-01-29
Abstract: PURPOSE:To enable the lock-in which can be pulled into a locking state almost instantaneously, by decreasing the lock-in time of a timing extracting circuit using a PLL circuit. CONSTITUTION:As shown by the output of a delaying circuit 20 in the diagram, the output of an AND circuit 19 is delayed by the circuit 20 down to a level less than the bit width of a received signal, i.e., 25nS lower than 31.25nS with this example. This delayed time is divided down to 1/8 by a counter 12, and the 2nd waveform of 50% duty which is inverted for every two frames is obtained as shown by the output of the counter 12 in the diagram. The 1st waveform delivered from a counter 11 and the 2nd waveform delivered from the counter 12 are fed to a phase comparator 13. The output of the counter 12 advances or delays if a VCO15 has fluctuation. This produces a difference of phase between the counters 12 and 11, and therefore the VCO15 is controlled to maintain synchronism. In the diagram the output of the circuit 19 has a phase advanced by the delay time of the circuit 20, i.e., 25nS in this example and is locked in case the perfect synchronism is obtained.
