A method includes determining a control setting and selectively stopping oscillation of an oscillator after a time period. The oscillator is configured to remain in an active mode after the time period. The method further includes applying the control setting to the oscillator.Martin Saint-Laurent...
Complications of timing recovery in an ATM receiver are overcome by employing a first phase lock loop including a phase comparator, filter, voltage controlled oscillator (VCO) and output counter to lock to systems clock reference (SCR) v... Barin G. Haskell,Amy R. Reibman 被引量: 244发表:...
Then, the receiver oscillator is properly tuned to its nominal frequency at each epoch without loss of lock. An automatic closed-loop frequency control ... TWY Meng - 《Gps Solutions》 被引量: 0发表: 2020年 Oscillator with frequency control loop Circuitry for providing an oscillating output sig...
frequency lockdoi:10.1007/1-4020-0613-6_7656In a device, such as an oscillator, the condition in which a frequency-correcting feedback loop maintains control of the output within the limits of one cycle. Note:Frequency lock does not imply...Martin H. WeikSpringer US...
This loop forces the voltage controlled oscillator (VCO) to operate at a frequency determined by the frequency reference and the divider’s division ratio. Sign in to download full-size image Figure 28.1. Typical Phase Lock Loop-Based Frequency Synthesizer. Level Shift Furnishes 0V to 30V Bias ...
The principle of operation is as follows: The loop is initially closed to lock the rf output, fOUT = N fREF. The modulating signal is turned on and at first the modulation signal is simply the dc mean of the modulation. The loop is then opened, by putting the CP output of the ...
