TIDA-01410: Sine Output Waveform

Part Number: TIDA-01410
Other Parts Discussed in Thread: LMX2594

Hi,

In the TIDA-01410 manual, I only see the generation of the square pulses.

Is it possible to generate the synchronized Sine waves output?

Regards,

Husnain

    Hello Husnain,

    This board does not have capability to generate sine wave outputs although synchronization is possible.

    If a sine wave is desired, look into using filters on the outputs, although, there is no guarantee these outputs would be synchronized.

    Hi,

    Okay, I understand that!

    Just a little question, the TIDA-01410 board does not produce sine wave but the PLL IC it is using LMX259 does produce sine wave?

    Hello Husnain,

    Sorry I didn't explain properly, the LMX2594 does not produce a sine wave intentionally. At higher frequencies typically the shape will be limited by slew rate but this device has very good performance even on the internal VCO.

    Again, in order to reach a sinewave output you will need to filter the waveform. Keep in mind that this can pose another problem as not all filters are the same and if you are trying to have synchronous waveforms the phase could easily be shifted from filter to filter.
