摘要: A phase-rotating phase locked loop (PLL) may include first and second loops that share a loop filter and a voltage controlled oscillator in order to perform the operation of a phase-rotating PLL, the first and second loops configured to activate in response to an enable signal. The PLL may further include a phase frequency detection controller configured to provide the enable signal to the first and second loops in response to a transition of a coarse signal that may be applied as a digital code.
