Low latency data handoff using phase rotation and clock gapping

Abstract

Aspects of the subject disclosure may include, for example, a device including a phase rotator configured to receive a read clock, a flip flop configured to obtain an incoming data stream, and a controller. The controller may be configured to control the phase rotator to perform phase rotation of the read clock based on information-carrying level transitions in the incoming data stream, cause a gapped read clock and an inversion of the gapped read clock to be derived in accordance with the phase rotation, where the gapped read clock being derived via gapping operations associated with the read clock, and output clock selection signals that enable the flip flop to selectively sample the incoming data stream using the gapped read clock and the inversion, thereby facilitating a data handoff between asynchronous clock domains. Other embodiments are disclosed.
