Techniques and mechanisms for a clock recovery circuit to generate a cyclical signal based on data signals which are susceptible to circuit switching jitter. In an embodiment, a clock recovery circuit comprises switch circuitry which receives a first signal representing a logical combination of multiple pulsed signals (which, in turn, are each based on a different respective differential data signal). The switch circuitry provides to latch circuitry of the clock recovery circuit a second signal based on the first signal. The latch circuitry generates a cyclical signal based on the second signal, and transitions the switch circuitry between an open-circuit state and a closed-circuit state. In another embodiment, the latch circuitry implements a predetermined and configurable time period between a transition of the cyclical signal and a next subsequent logic state transition of the cyclical signal.

Clock recovery circuit and method of operating same

Described is an apparatus comprising: first and second processing cores; and a PCU which is operable to: generate a first VID for an off-die regulator external to the apparatus, the first VID resulting in a first power supply for the first processing core; and generate a second VID different from the first VID, the second VID resulting in a second power supply for the second processing core. Described is an apparatus comprising: a plurality of power-gate transistors controllable by a digital bus, the plurality of power-gate transistors operable to provide a first power supply to a processing core, and to receive a second power supply as input; an ADC to receive the first power supply and to generate a digital output representative of the first power supply; and a controller to receive the digital output representative and to generate the digital bus for controlling the plurality of power-gate transistors.
