    摘要： A phase locked loop includes: a loop filter; a voltage controlled oscillating unit configured to output a frequency varying according to an output voltage of the loop filter; a frequency down-converting unit configured to down-convert an output frequency of the voltage controlled oscillating unit according to a band of the output frequency of the voltage controlled oscillating unit; and a frequency divider configured to divide a frequency down-converted by the frequency down-converting unit. The output frequency of the voltage controlled oscillating unit varies according to the output voltage of the loop filter and a control signal compensating the frequency down-converted by the frequency down-converting unit.

    摘要： Provided is a satellite broadcasting terminals. The satellite broadcasting terminal includes: a first antenna receiving a radio signal of a first band or a second band; a second antenna receiving a radio signal of a third band; a first stream demodulating unit demodulating a first stream signal received through the first band; a second stream demodulating unit demodulating a second stream signal received through the second band; a playing unit playing the demodulated first or second stream signal; and a gap filler receiving unit selectively providing the first stream signal to the first stream demodulating unit in response to a radio signal intensity of the third band, the first stream signal being received through the third band.
