Abstract
Data and clock bits are sampled by use of two delay means such as shift registers which are enabled at a clock rate which is set so that a first such delay means coupled to receive the bits includes no more than one bit therein at any time. The receipt of a bit substantially at the midway point of the second delay means, which is coupled serially to receive bits from the first delay means, causes a sampling signal to be generated in response to which a determination is made as to whether another bit has been received by the first delay means. Further logic is provided to recover the data bits.
