DAC37J84: Phase noise

Part Number: DAC37J84

Dear colleagues, my customer is interested in phase noise of DAC37J84 - dBc/Hz

Where is it possible to get the data?

Thanks,

Vladimir.

    Hi, Vladimir!

    Look at page 13 of this document, there you can find spectral density of noise
    www.ti.com/.../dac37j84.pdf
    at page 105 of same document please find §8.2.1.2.4 where describes minimization of PLL phase noise.

    But in general your question is not too easy because of while we are using DAC our noises depends of a long circuit from the XTAL and PLL+VCO to the DAC IC.

    Best regards!
