| Abstract: | This paper presents the implementation of a 434MHz local oscillator for a superheterodyne transceiver by using an integrated phase locked loop chip-Si4133. The methods of the center frequency adjustment and the impedance matching for output are introduced. In addition, the programming method to N and R fractional frequency registers using I2C bus interface of chip, three key factors and control methods for affecting phase locked loop output phase noise, and debugging circuit using DLPortIO software are also... |
