AD9125 internal VCO phase noise


We are using AD9125 for our communication system transmitter.

The upconversion to IF is also done using the complex mixer within the DAC.

The reference clock to DAC ia 100MHz and we use the internal PLL to generate the internal DAC sampling clock of 400MHz.

The IF output phase noise is dependent on the phase noise of the internal DAC clock.

The datasheet doesn't mention the phase noise of internal VCO.
