  • Minimizing recovery time
    Patent number: 6222420
    Abstract: A circuit (70) includes a reset stage (72) and a Phase-Locked Loop (PLL) device (73). The PLL device (73) includes a phase detector (74), a charge pump (75), a filter (76), and a Voltage-Controlled Oscillator (77). The reset stage (72) receives a reference signal and is connected to the phase detector (74). The phase detector (74) receives the reference signal and a feedback signal. When the reference signal switches from a first clock signal to a second clock signal, the reset stage (72) places the phase detector (74) in an inactive state until the reset stage (72) detects a falling edge in the reference signal.
    Type: Grant
