Abstract
An integrated circuit ('IC') includes a phase-locked loop ('PLL') with a controllable oscillator embedded in the integrated circuit. A phase-lock circuit provides a lock control signal to the controllable oscillator; and a digital-to-analog converter (“DAC”) provides an oscillator adjustment signal to the controllable oscillator according to a digital code. The digital code is generated by an adjustment circuit configured in the fabric of a programmable logic device, or embedded in the IC, for example. In a particular embodiment, the DAC adjusts the PLL to reduce differential mode voltage in the phase-lock circuit.
