Digital control circuit and method for clock signal production in integrated circuits has phase detector, control circuit filter and two phase generators

摘要

A digital control circuit for clock signal production comprises at least one phase detector (PD,DL,P11,SDL,P12) with reference signal input (12) and feedback input (14), at least one control circuit filter (DLF) with corrector signal input (16) and control output (18,24) and two phase generators with clock-separated outputs (22,28). An independent claim is also included for a method for clock signal production comprising the above.
