DAC3283: Design Inquiry

Part Number: DAC3283

Tool/software:

Hi Team,

I'm planning to use the DAC IC DAC3283 in my board.

I have one query regarding the IC. I want an input Frame Sync or Clock Sync signal which must be coming from the processor in order to sync all my clock circuitry in the board, i want the DAC ICs with an clock sync option.

Does the above mentioned DAC support any input clock sync option. 

If not please suggest any other DAC IC with 16bit resolution, 34MSPS speed, 2 channel is available for my application.

Regards,

Abhishek

    Hello, 

    The DAC3283 supports the frame sync input and OSTR signal to synchronize the input/output FIFO for the DAC3283.

    There is no option to provide an output to synchronize your clock circuitry. You will need to look at other DAC options.

    I will refer you to our other product groups for reference.

    Hi Kang, 

    We don't have any devices in the precision DAC portfolio that reach 34MSPS.

    It looks like Abhishek is looking for the DAC to have a sync input, not output. The processor will have an output. 

    Best,

    Hi Team,

    I want a DAC to have sync signal coming from the processor. For DAC3283, i didn't see any SYNC pin. Can you tell which pin should be used as SYNC input pin.

    Regards,

    Abhishek

    Hello Abhishek,

    For the DAC3283, the FRAME signal will synchronize the FIFO input pointer. There is no pin at the DAC3283 to synchronize the clock circuitry.

    I would like to check what do you mean when you say you need a input signal to sync your clock circuitry. Would you kindly share your block diagram or concept so the folks here can help you find the best suitable part. The definition of clock circuitry sync has many meanings to different applications.
