GLITCH-FREE DIGITALLY CONTROLLED OSCILLATOR CODE UPDATE |
摘要 |
A glitch-free digitally controlled oscillator (DCO) code update may be achieved by synchronizing the transfer of the DCO code update to a logic state transition of a pulse in the DCO clock output signal such that the code update may be achieved while the DCO delay chain remains in the same logic state. A state machine may provide the DCO code update and a pulsed update signal to a timing circuit. The DCO code update may be aligned with a pulse in the pulsed update signal. The timing circuit may generate a DCO code update enabled signal upon alignment of the pulse in the pulsed update signal with a state transition of a pulse in the pulsed DCO clock output. The DCO code update enabled signal may be aligned with a state transition in the pulsed DCO clock output to permit a glitch-free DCO code update. |
