| titleOfInvention | Apparatus and method for controlling phase of multiple phase locked loop(PLL) module based on Global Navigation Satellite System(GNSS) |
| abstract | The present invention relates to an apparatus and method for controlling a phase of a GNSS-based multiple PLL module, and more particularly, to a GNSS-based phase control apparatus and method for a GNSS-based multiple PLL module. A plurality of PLL circuits corresponding to a plurality of reference clock generators, respectively, for fixing phases using a reference clock output from a reference clock generator; And a control module for controlling a phase difference between clock signals output from the plurality of PLL circuits, each of the plurality of PLL circuits comprising: an oscillator (VCXO) for outputting a clock signal; A frequency divider for dividing a clock signal output from the oscillator; And a phase comparator for comparing a phase of a reference clock output from the reference clock generator with a phase of a clock signal divided in the frequency divider. According to the present invention, a phase difference between output clocks between a plurality of PLL modules can be minimized to maintain high accuracy. In addition, the accurate reference clock synchronized with the precise clock (1PPS) provided by the GNSS navigation satellite can be used to obtain an economic effect of not using an expensive high-precision rubidium oscillation element. |
