Abstract
A method of measuring a clock signal includes launching an edge of a timing signal on a first edge of the clock signal, outputting an edge of a capture signal on a second edge of the clock signal, receiving the edge of the timing signal and the edge of the capture signal at a time-to-digital converter (TDC), and measuring a time delay using the TDC, wherein the time delay is between a time the edge of the timing signal is received at the TDC and a time the edge of the capture signal is received at the TDC.
