Abstract

Space laser communication is moving in a wider bandwidth, greater distances, is more accurate and more narrow laser communication beam direction, faster bandwidth as well as communication interface chip high-speed clock more demanding requirements of the low frequency noise, and good reliability, small size and low power consumption characteristics. Production of ADI's ADF4350 integrated voltage-controlled oscillator (VCO) bandwidth frequency synthesizer just to meet this requirement clock frequency This paper describes the basic principles and operating characteristics of the broadband frequency synthesizer. In this paper we use CPLD to control the ADF4350 and give a control electric circuit with CPLD structure and based on Verilog program. Simulation and experimental results show that the lock-in effect is good, easy to control, and reliable performance. It is able to generate stable clock, suitable for applications in laser communication.
