Frequency swept source using xilinx dds compiler

Abstract- this paper presents a module which basically is a frequency swept source (chirp signal), which sweeps from 1mhz to 10 mhz in 10 microsecondsthe module was designed by using the dds ip core in xilinx. I am also trying to generate a waveform with dds 60 but for a phased locked loop, i am trying to configure the dds compiler but no luck, i want an output of 2pi1/500 any help would be much appreciated. Direct digital synthesis (dds) is a technique for using digital data processing blocks as a means to generate a frequency- and phase-tunable output signal referenced to a fixed-frequency precision clock source.

• debug the design using vivado logic analyzer in real-time, and iterate the design using the vivado ide and a kc705 evaluation kit base board that incorporates a kintex®-7 device • analyze high-speed serial links using the serial i/o analyzer. Hello, i'm currently trying to implement a simple low-pass filter using the fir compiler available in the ip catalog my design is very basic, i've generated a sine wave using the dds ip .

The design of signal source using xilinx system generator tool is more convenient and cheaper for the output frequency of dds compiler is calculate by equation (1. Dear forum members, i have a question about the dds compiler i already generated 40 mhz sinusoidal digital signal from the dds compiler using 320 mhz input clock. I am using labview fpga2011 and flexrio 7965r (ie virtex5 sx95t) i have compiled a sinusoid generater using the built in xilinx coregen ip named 'dds compiler' the output of dds compiler is sent to the host vi using dma fifo. In project mode, using the vivado ide gui, you use the vivado ide to create a project and implement the design in a xilinx 7 series fpga additionally, chapter 4 shows you how to do the same simulation steps in a non-project mode.

Frequency chirps generated with the dds linear sweep unit in comparison to the ram linearized chirps, b = 10, 50, and 83 mhz. This xilinx® vivado™ design suite tutorial provides designers with an in-depth introduction to create a new project for managing source files, add ip to the.

Linear frequency modulated signal using multi-dds technol- ogyradar is an object detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. Logic simulation wwwxilinxcom 7 ug937 (v 20131) march 20, 2013 a simple testbench (testbenchv), to simulate the sine wave generator design that: generates a 200 mhz input clock for the design system clock, sys_clk_p. The dds compiler is used to generate a 20msps sine wave the output of the dds compiler is converted to a different value and it is scaled to 1 and then sent to the scope lock where we can see the output.

  • Figure 8: example plot for dithered dds simulation with frequency sweep in figure 8, the synthesized signal is swept over a range of frequencies starting from 00311 to 00415 hz there are ten tones in the sweep separated in frequency by 000104 hz.

Dds is a method of generating timing signals from a clock source with programmable frequency it is used in all sorts of places such as frequency hopping, signal synthesis, medical imaging systems, radio receivers, plls, test equipment, the list goes on and on.
