  • Patent number: 7868949
    Abstract: In order to further develop a circuit arrangement (100; 102; 104; 106) and a method of locking onto and/or processing data, in particular audio, television and/or video data, by means of at least one phase locked loop (40), wherein phase information is detected by means of at least one phase detector (44), in particular following the arrival of at least one rising edge and/or falling edge of at least one analog input signal (50; 50), at least one increment (24) is determined by means of at least one loop filter (30), to which the output signal (56) which is output by the phase detector (44) is fed, and at least one ramp oscillator (46) is fed the increment (24) which is output by the loop filter (30), such that inter alia the circuit arrangement (100; 102; 104; 106).
