Abstract: A clock generator is disclosed that includes a lock detector. The lock detector is configured to generate a lock signal based on control signals of a phase lock loop circuit that generates an output clock of a desired frequency that is phase locked to a reference clock. The lock detector generates a mismatch signal based on a comparison between the phases of the reference clock and the output clock to generate a compare result. The lock detector delays the compare result by a time period Td and AND the delayed compare result with the compare result to generate the mismatch signal. The lock detector includes a lock-counter that counts a number of reference clock cycles when the mismatch signal remains at 0. The lock signal indicates that a lock-state is achieved when the number of counted reference clock cycles equals a set-value.

Abstract: An apparatus and method are disclosed for generating one or more clock signals. A clock signal is generated based on pattern signals and a reference clock signal. When the reference clock signal transitions high, the state of a first pattern signal is output, and when the reference clock signal transitions low, the state of a second pattern signal is output. Successive states of the first and second pattern signals, selected according to the reference clock signal, provide the generated clock signal.
