Title: Phase frequency detector and phase locked loop circuit incorporating the same
Inventor: AKIYAMA CHIYOJI
IPC: H03D13/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To attain phase synchronization in a short time, even when frequencies in the circuit are set apart from each other by applying a modification taking a frequency difference into account to a phase error signal. SOLUTION: A jump detection section 30 detects discontinuous jump of a phase error signal, when frequencies used by the circuit are apart from each other and a detection signal of the detection section 30 is made to transit the state of a state storage section 32. A storage section 34 corrects the phase error signal, in response to a state of the state storage section 32 to obtain a frequency phase error signal. According to this method, the frequency phase error signal resulting from adding a frequency error to a phase error is obtained and is used for controlling a PLL, so as to attain synchronization in a short time even when frequencies of the two signals are set apart from each other.
