Jitter attenuators (100) with a phase detector (104) to control a crystal oscillator to remove jitter wherein the phase detector includes both a sequential phase/frequency detector (200) of low transistor count and an arrangement of two sequential phase/frequency detectors (198 and 200) to increase gain and two drivers for the crystal oscillator.
[ I claim:] [4.] A phase detecting system comprising:a first phase-frequency comparator having at least two inputs, one input connected to a first node and another input connected to a second node, said first phase-frequency comparator having an output;a second phase-frequency comparator having at least two inputs, one input connected to an output of a first inverter and another input connected to an output of a second inverter, wherein an input of said first inverter is connected to said first node and wherein an input of said second inverter is connect...
