Title: Lock discrimination circuit and pll frequency synthesizer
Inventor: NAKAMURA SUSUMU
IPC: H03L7/095
Filed: 2002-08-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lock discrimination circuit that surely prevents dissidence between a discrimination result of the circuit and an operating state when a reference signal is stopped.  <P>SOLUTION: The lock discrimination circuit receives a reference signal DX and a phase error signal LOCK between a comparison signal fp and a reference signal fr to perform lock discrimination as to whether or not the phase of the comparison signal is coincident with the phase of the reference signal. A voltage adder 51 receives and monitors the reference signal DX given to the lock discrimination circuit and generates a reference signal detection signal DXA denoting whether or not the reference signal DX is stopped. An output signal of the voltage adder 51 is given to clear terminals of FFs 3,4,5 being components of a lock detection section for detecting whether or not locking is made. When the reference signal detection signal DXA of the voltage adder 51 goes to 'L' (stop of the reference signal DX) in the lock detection section, the FFs 3,4,5 are cleared and provide an output of a 0 level from the output terminals Q. As a result, a lock discrimination output signal LD goes to 'L' (unlock state).  <P>COPYRIGHT: (C)2004,JPO
