The latest data acquisition system running at the Jicamarca Radio Observatory for the main radar has been used for more than five years now. Although there are no major inconveniences on the performance there have been some problems with internal interferences which are usually unpredictable and related to the PCB design, the noise floor can be different between channels too. So there are some chances of improvement developing a new approach. We propose a new design based on a high speed JESD204B data interface; the digital signal processing and custom acquisition logic will be implemented inside an FPGA capable of managing the JESD204B high-speed interface. This will give us the flexibility of implementing digital blocks inside the FPGA to improve the performance of the receivers, we will gain scalability to perform on a much higher bandwidth and the PCB will be very much simplified which will reduce the manufacturing costs, design time, and development time.
