Abstract
A high performance CDR circuit. The circuit includes a first and second sampler, a first and second charge-pump coupled to the first and the second sampler, a capacitor coupled to the first charge pump, and a filter coupled to the second charge pump. A VCO circuit is coupled to the first charge pump and the second charge pump, wherein a path for setting a frequency is provided by the first charge pump and the capacitor, and wherein a path for phase is provided by the second charge pump, wherein a voltage of the capacitor is stable to enable the VCO to tolerate CIDs.
