Pulse detector for determining phase relationship between signals |
摘要 |
A pulse detector detects if a clock pulse signal is in phase with a reference clock pulse signal in an efficient manner with very high accuracy. The pulse detector includes a first delay unit adapted to receive an input clock pulse signal and to delay the input clock pulse signal by a first pre-specified delay for output as output clock pulse signal, and a second delay unit adapted to delay the output clock pulse signal by a second pre-specified delay. A sampling unit is adapted to sample the input clock pulse signal and the output of the second delay unit at a sampling time defined by a reference clock pulse signal and to output the samples for phase delay indication.
