Design of dds signal generator based on fpga
WebDDS running in parallel inside the FPGA, each operating at 250 MHz with each DDS operating at 250 MHz with 36 degrees phase-shift with adjacent DDS. The 10 sets of DDS share the same waveform look up table (LUT). In the end, they serialize their output into two sets of 14 channels, 1.25 Gbps high speed LVDS data streams, and send it to the DAC.
