Abstract: A system includes memory and at least one processor coupled to the memory and configured to receive a phase detector (PD) error signal. The PD error signal indicates a leading clock signal of at least two clock signals. The at least two clock signals are generated based on an input clock signal and a voltage control signal. The at least one processor receives a toggling signal indicating whether one of the at least two clock signals is toggling between clock cycles of the input clock signal. A code value is generated based on the PD error signal and the toggling signal. The at least one processor causes generation of the voltage control signal based on the code value.

Abstract: According to various embodiments, a differential transmitter includes a driver and a predriver. In various embodiments, the predriver may include pull-up transistors and pull-down transistors configured in various ways to produce a staged output signal during a pull-up transition, wherein the higher bits of the input signal are switched slower in comparison with the lower bits of the input signal, while at the same time maintaining the simultaneous pull-down transition among all the bits. In various embodiments, the staged output of a predriver may further be dynamically disabled during a deemphasis exit transition. Other embodiments may be described and claimed.
