Abstract:
1. A data recovery apparatus comprising: a plurality of oscillators adapted to receive a serial bit stream, and to generate data detection signals conveying first series of pulses during first time periods for which the serial bit stream conveys a logical 1, and conveying second series of pulses during second time periods for which the serial bit stream conveys a logical 0; edge detection circuitry operatively coupled with the plurality of oscillators, wherein the edge detection circuitry is adapted to receive the data detection signals, to detect transition edges of the first series of pulses and the second series of pulses within the data detection signals, and to generate 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; and first data storage operatively coupled with the edge detection circuitry, wherein the first data storage includes a plurality of bit locations, and the first data storage is adapted to receive the data storage signals, to write a logical 1 into an unmasked subset of the plurality of bit locations in response to receiving a first indication of a detected transition edge in the first series of pulses, and to write a logical 0 into the unmasked subset of the plurality of bit locations in response to receiving a second indication of a detected transition edge in the second series of pulses.
