Patent number: 9124415Abstract: A clock generator with glitchless phase adjustment having a phase locked loop with a controlled oscillator providing an output representing a phase value. One or more output modules generate one or more output clocks from the output. One or more adjustment modules add a requested phase adjustment to an output clock. The phase adjustment modules are configured to break the requested phase adjustment into smaller increments and apply the increments to an output clock generated in said at the output modules one cycle at a time.Type: GrantFiled: January 14, 2015Date of Patent: September 1, 2015Assignee: Microsemi Semiconductor ULCInventors: David Colby, Joep De Rijk, Paul H.

Patent number: 9094185Abstract: A digital phase locked loop has a phase acquisition module that outputs a first phase value representative of the phase of a reference signal expressed with respect to an internal phase reference. A phase offset write module convert a phases offset commanded from an external source into a phase offset correction value expressed with respect to the internal phase reference. A phase offset controller sums the phase offset correction values to produce a second phase value, which is added to the first phase value to produce a third phase value expressed with respect to the internal phase reference. A digital controlled oscillator (DCO) outputs a fourth phase value expressed with respect to the internal phase reference. A phase detector outputs a fifth phase value representing the difference between the third and fourth phase values. A loop filter derives a frequency offset for the DCO based on the fifth phase value. An output module generates one or more output clocks from the fourth phase value.Type: GrantFiled: January 14, 2015Date of Patent: July 28, 2015Assignee: MICROSEMI SEMICONDUCTOR ULCInventors: Paul H.
