Abstract
Techniques and mechanisms for determining calibration information based on tuning of a ring oscillator circuit formed with two integrated circuit (IC) dies. In an embodiment, an oscillator circuit comprises an in-series arrangement of delay circuits including a first one or more delay circuits of a first die, and a second one or more delay circuits of a second die. Respective circuitry of the first die and the second die performs tuning to match an oscillation frequency of the oscillator circuit with a reference frequency. An operational setting of the tuned oscillator circuit is provided to calibrate transmitter circuitry of the first die and the second die. In another embodiment, tuning of the oscillator circuit is further based on tuning of a local oscillator circuit of one of the first die or the second die.
