Abstract
A phase locked loop having a charge pump is described. The charge pump has circuitry to select a mode for each semiconductor chip from a plurality of modes to enhance yield. Nine unique modes are defined from which a selection is made for each chip. The selected mode mitigates effects of device mistracking anomalies for each chip. A method is provided to show how the modes are determined and prioritized.
