ABSTRACT:
An apparatus for generating an output signal whose frequency is lower than the frequency of an input signal is disclosed. The apparatus includes a chain of frequency dividing cells where each cell has a definable division ratio. Furthermore, the frequency dividing cells include a clock input for receiving an input clock, a divided clock output for providing an output clock to a subsequent frequency dividing cell, a mode control input for receiving a mode control input signal from the subsequent frequency dividing cell, and a mode control output for providing a mode control output signal to a preceding frequency dividing cell. The apparatus may further includes a logic network having one or more inputs where each input is connected to a mode control input of one of the frequency dividing cells.
