【Abstract】 The high-speed high-resolution DAC module is designed by using FPDP bus and high-speed DAC chips to genrate a SAR and the pulse radar signal in real time. In order to achieve the performance of the DAC, the important signals are carefully processed, such as power, CLK and so on. This paper uses FPDP for the SAR signal simulator, in which FPDP transmits data to a DAC module. The FPDP can meet the needs of SAR data rate. FPGA implements the FPDP bus interface, DAC control and data format transform, thus simplifing the system design.更多还原
