摘要：
An apparatus comprising a phase lock loop (PLL) and a charge pump. The PLL may be configured to generate an output signal in response to an input signal. The charge pump may be configured within the PLL and be configured to (i) pump-up the input signal, (ii) pump-down the input signal or (iii) enter tri-state in response to a control signal.
