Patent ID: 7221724

Claim:
A precision timing generator, comprising: a reference clock signal; a clock generator generating from the reference clock signal a plurality of clock signals of equal frequency, each clock signal being offset from another one of the clock by a predetermined phase; a first selector circuit selecting a first group of two clock signals, the selected clock signals being offset from each other by the predetermined phase; a first interpolator circuit receiving the first group of selected clock signals and associating with each clock signal a predetermined weight, and providing a first resulting clock signal that is offset from each of the selected clock signal by less than the predetermined phase and in proportional to the predetermined weights; a second selector circuit selecting a second group of two clock signals, the selected clock signals being offset from each other by the predetermined phase; a second interpolator circuit receiving the second group of selected clock signals and associating with each clock signal a predetermined weight, and providing a second resulting clock signal that is offset from each of the selected clock signal by less than the predetermined phase and in proportional to the predetermined weights; and a logic gate applying a logic operation on the first resulting clock signal and the second resulting clock signal to provide a precision clock signal.
