Abstract:
1. An integrated circuit (IC) comprising: a plurality of shift registers, wherein each shift register is coupled to a subsequent shift register through a multiplexer; a multiplexer controller operable to activate a subset of shift registers within the plurality of shift registers, wherein activating the subset of shift registers depends on a divisional factor; a pattern controller operable to generate a control signal that is to be transmitted to the plurality of shift registers, wherein the control signal sets up the subset of shift registers for dividing a frequency of a signal by the divisional factor; and a strobe generator operable to generate a signal that triggers the pattern controller to send the control signal to the plurality of shift registers, wherein the strobe generator comprises a first flip flop, a second flip flop coupled to an output of the first flip flop, and an AND gate receives the output from the first flip flop and an output form the second flip flop.
