Abstract
A representative method of serial link transceiver without external reference clock is disclosed. The method includes: receiving an incoming signal; generating a local timing under control of a control code; generating a temperature sensor code by sensing a local temperature; generating a logical signal by detecting a presence of the incoming signal; adjusting the control code in a closed loop manner to make the local timing match that of the incoming signal and recording the control code and a value of the temperature sensor code as part of a template when the logical signal is asserted; and synthesizing the control code in accordance with the template when the logical signal is not asserted.
