Serializer and Deserializer (SerDes) for High Speed Serial ...

In a high-speed SerDes transceiver, the transmitter clock is usually generated by a CMU that synthesizes high-frequency clock from a low-frequency but very accurate oscillator such as a quartz oscillator [H.8] or even an atomic clock [H.54]. When frequency is locked, the frequency lock loop (FLL) is usually frozen (or switched off), and the PLL begins to align the clock phase to the incoming ... ................
