For IEEE 1588 applications, the … WebOct 22, 2024 · A recovered clock will be generated by phase aligning the reference clock to the transition on the incoming data signal. This is called Clock Recovery. The re-timing of incoming data signals using the recovered clock is called Data Recovery. Together, this is called Clock Data Recovery, or CDR. In other words, the role of the CDR is to recover ...

WebMar 11, 2024 · There's many ways to do it, but typically, you build a control loop, in which you strive to put the zero crossings on average at the same time. A zero crossing is too early – notch the local clock to run a tiny bit faster. A zero crossing is too late – slow down the local clock a tiny bit. WebThe recovered clock frequency is half of the above 125 MHz figure, that is, 62.5 MHz (quite unpopular in designs). Although synchronized with the Master Clock, its phase alternates during transmission (see IEEE 802.3-2004, section 36.3.3 for details).
