Reference-less frequency detector |
摘要 |
Embodiments provide a reference-less frequency detector that overcomes the "dead zone" problem of conventional circuits. In particular, the frequency detector is able to accurately resolve the polarity of the frequency difference between the VCO clock signal and the data signal, irrespective of the magnitude of the frequency difference and the presence of VCO clock jitter and/or ISI on the data signal.
