Abstract
An open loop clock divider circuit includes (a) a first divider configured to receive an incoming clock signal and output a first divided clock signal, (b) a flying-adder synthesizer configured to fractionally divide the first divided clock signal and output a fractionally divided clock signal, and (c) a second divider configured to receive the fractionally divided clock signal and output a second divided clock signal. The open loop clock divider circuit advantageously provides a fractional divider in which there is no feedback loop between the source frequency (f) and the destination frequency (f). Methods of generating a divided clock signal involving the open loop clock divider circuit are also disclosed.
