Abstract: 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.
