This application is directed to managing signal timing on a serial data interface of an electronic device. The electronic device includes an interface controller configured to drive an output interface. The interface controller receives a first clock signal, and determines a low cycle length of the first clock signal. The interface controller dynamically determines a duty cycle of a second clock signal based on the low cycle length of the first clock signal. The second clock signal having the duty cycle is generated by the interface controller, and provided to the output interface. In some embodiments, the interface controller determines an outgoing delay, an incoming delay, and a sampling tolerance time. A difference may be further determined between the low cycle length of the first clock signal and a sum of the incoming delay and the outgoing delay, and applied to control the duty cycle of the second clock signal.

Systems and methods for detecting coolant leakage in direct liquid cooling systems are disclosed. Liquid coolant is flowed through cold plates that are attached to adjacent processors. Sensor readings of the processors are formed into a differential signal. Distribution of the differential signal is determined. Leakage of the liquid coolant is detected from the distribution of the differential signal.
