    As you are using a 275 MSPS DAC I take it you want it at a high rate.

    Create a look-up table of a single-quadrant sine.
    The rest as the same as you do with Parallax Prop built-in table

    Sine Table

    The sine table provides 2,049 unsigned 16-bit sine samples spanning from 0° to 90°, inclusively (0.0439° resolution).
    Sine values for all other quadrants covering > 90° to < 360° can be calculated from simple transformations on this single-quadrant sine table.

    1. Connect the data and write/clock signals to some GPIO pins.
    2. Write appropriate values to the pins (alternating to data and clock).
      Timers and/or DMA can help with this.

    What exactly do yo have a problem with?
