  • Phase locked loop with a lock detector
    Patent number: 6133769
    Abstract: A phase locked loop comprises a phase locking circuit (16) which includes a phase/frequency detector (18) capable of outputting up and down signals to a charge pump (22) through separate signal paths (24, 26) and a phase lock detector (34) coupled to receive the up and down signals. The phase lock detector (34) determines the difference between the up and down signals from the phase/frequency detector (18) and in response generates a phase lock indicator signal PLL.sub.-- OUT.
