No, the AD9779A is limited by the data sheet spec.
Here we have a request in the application of high speed DAC. We’dlike to use AD9779A, it’sthe dual DACs for I and Q output. If we use one port of it just as a direct IFDAC, the bandwidth is 100MHz, center frequency is 312.5MHz, is it possible?
On Page 46 of AD9779A datasheet there is a paragraph "INPUT DATA REFERENCED TO DATACLK". In this paragraph there is showed the Figure 82. Is this Figure 82 valid also if I set 4x interpolator on the AD9779A ? In other words, if I use 4x interpolator,…
What is the max current of AD9779A CVDD18 power? the max current of DVDD18 power?
480Mhz is the 4th harmonic of the 120Mhz clock input. Clock spurs like this are normal outputs of the AD9779A. A filter following the DAC will attenuate this signal.
The AD9779A automatic timing optimization mode does not work. Please do not use it.
The resolution of Data Timing Margin is 190ps.
I would like to interface the AD9122, AD9125, AD9788, AD9779A (IF-DACs) with an analog quadrature modulator. Which ones do you recommend?
