ABSTRACT:
A hybrid analog-digital phase error detector (107) is utilized for detecting a phase error between first and second clock signals (132, 104). Digital and analog phase error detectors (108, 116) are connected to the first and second clock signals (132, 104), and are utilized for producing digital and analog phase error values (110, 118). The digital and analog controllers (112, 120) connected to the digital and analog phase error detectors (108, 116) execute digital and analog control algorithms based on the digital and analog phase error values (110, 118) to produce digital and analog control signals (114, 122). A summer (124) connected to the outputs of the digital and analog controllers (112, 120) combines the analog control signal (122) and the digital control signal (114) to produce a composite control signal (126) representing the phase error.
