Patent ID: 7804349

Claim:
An apparatus for providing timing signals, comprising: a master period generator comprising: a first resettable counter, resettable by a selectable period signal and configured to count cycles of a received clock within a period of the selectable periodic signal; a memory storing a first period value and a second period value, the first and second stored period values derivable from a relationship between the received clock and the selectable periodic signal; a master detector circuit providing a coincidence signal indicative of an output of the first resettable counter coinciding with the stored first period value; a signal conditioning circuit providing the selectable period signal in response to the coincidence signal, the selectable period signal having a non-integer relationship with respect to the received clock cycles; a residue circuit updating, responsive to the selectable period signal, a residue value according to the stored second period value and a current residue value; and a second resettable counter, resettable by a beginning-of-time signal and configured to count cycles of the received clock since the beginning-of-time signal.
