Working Principles

The DS125DF111SQ operates by receiving high-speed serial data signals through its differential input pins. It conditions the received signals using equalization and pre-emphasis techniques to compensate for signal degradation. The clock and data recovery circuitry extracts the clock and data information from the received signals. Jitter attenuation algorithms are applied to reduce any timing variations in the recovered signals. The processed signals are then output through the differential output pins.
