Abstract
In one embodiment, a monitor circuit is disclosed. For example, the monitor circuit includes a first delay line circuit having a plurality of delay taps for receiving data from a data channel, and a second delay line circuit having a plurality of points for sampling the data received from the first delay line circuit, where the plurality of points comprises an input point, a middle point and an output point. The monitor circuit further includes a voltage control circuit for providing a control voltage to the second delay line circuit, and a data compare circuit for comparing a data value of the input point and a data value of the middle point to produce a first out-of-bounds signal, and for comparing the data value of the middle point and a data value of the output point to produce a second out-of-bounds signal.
