| Abstract: | With the development of data acquisition system to high-speed data acquisition system, the sampling clk that the high-speed sampling chip needed requires high quality. So this paper introduced a clock circuit design based on ADF4350, the paper detailsADF4350’s function and configuration registers, also introduced detail application of ADF4350 in the 960MHz high-speed data acquisition system, given the specific value of configuration register. And used the Xilinx Corporation ISE Chipscope Pro to capture the samping data, calculated ADC chip’s ENOB, the measured data indicated that the clk output of ADF4350 has high quality, high stability, and meet the design requirements. |
