Abstract:
A clock-data recovery doubler circuit for digitally encoded communications signals is provided. A window comparator includes two thresholds. A clock output is created by the window comparator and also used internally as feedback. Based on the clock output, the window comparator circuit collapses the thresholds while sampling input Bipolar return to zero data.
