Conventional receiver architectures are based on either frequency/phase
tracking or oversampling. Both receiver types typically employ sensitive
analog circuits, which create noise, consume power and utilize valuable
space in their implementation. The invention adopts a novel approach to
phase/frequency tracking that utilizes the edges or zero crossings of the
input data waveform to effectively track the remote transmitter clock
phase/frequency. This methodology minimizes the use of analog circuitry,
thereby reducing the noise domain and the substrate space required for
implementation of a tracking device.
