Abstract
Embodiments of data recovery apparatus include oscillators, edge detection circuitry, and data storage. The oscillators generate data detection signals, which convey first series of pulses during time periods for which a serial bit stream conveys a logical 1, and second series of pulses during time periods for which the serial bit stream conveys a logical 0. The edge detection circuitry detects transition edges of the first and second series of pulses, and generates data storage signals that include first indications of detected transition edges in the first series of pulses and second indications of detected transition edges in the second series of pulses. In response to receiving a first indication, a logical 1 is written into an unmasked subset of data storage bit locations. In response to receiving a second indication, a logical 0 is written into the unmasked subset of bit locations.
