ABSTRACT:
A programmable phase adjuster spans a clock signal's period with N linearly distributed phase steps. The resulting phase adjust resolution is finer than that of an inverter delay for a given process. Enhancement of the phase resolution of a phase picker CRM architecture enables use of the architecture for recovering clock signals from high data rate data streams in a way that minimizes power and area and allows optimization for multi-channel applications.
