Abstract:

Presents the working principle of Integrated PLL chip Si4133, this paper presents the implementation of a 375MHz local oscillator for a super heterodyne transmitter/receiver by using Si4133.Using programming method to set the divider register Internal chip. In addition, this paper discuss the methods for decreases the phase noise. Debugging circuit using ICCAVR software , and show the debugging results. Facts show that the phase noise and spurious of the frequency synthesizer is low, and it is practical.
