Continuous Wave Phase-aligned Multitone Generator: DC-to-6-GHz RF-Sampling DAC Reference Design


Design files


The TIDA-01084 reference design demonstrates the use of RF sampling DAC to generate continuous phase-aligned multitone waveforms. With four 48-bit independent NCOs, the 14-bit, 9GSPS DAC38RF83 can generate four CW tones placed anywhere within the first Nyquist zone or up to 6 GHz in the second.

This reference design covers the theory of operations, explanation of the GUI, and directions for programming NCOs to generate the tones without the requirement of an external pattern generator. This design demonstrates an easy-to-use method which greatly simplifies and reduces the bill of materials (BOM) for continuos waveform generation.

  • Generates multiple CW tones in the first nyquist and up to 6 GHz supported in the second
  • Digital Single-Side Band Upconversion
  • Multitone phase alignment synchronization
