Abstract
A fast timing acquisition device for relay type frequency-locked circuits and phase-locked circuits, which comprises a conversion detector, a voltage control oscillator, a circuit filter for phase-locked circuits, a first low-pass filter, a 90° phase converter, a second low-pass filter, and a plurality of multipliers; which is characterized in further comprising a frequency delimiter comprising: a high-pass filter coupled to the first circuit; a second circuit coupled to the high-pass filter; a third low-pass filter coupled to the second circuit; a Schmitt inverter coupled to the third low-pass filter; and a switch device coupled to the Schmitt inverter; thereby the frequency delimiter enables the timing acquisition device achieving a stable and fast timing acquisition.
