We are offering an alternative part, the AD9125 for new designs. As for the plan to obsolete it, I will get back to you on this.
The AD9125 is a 16 bit CMOS version of the AD9122 so this perhaps could be a useful replacement part if you wish to not have to drive differential.
I would like to interface the AD9122, AD9125, AD9788, AD9779A (IF-DACs) with an analog quadrature modulator. Which ones do you recommend?
Yes, this is one of the common usages of the DAC+ IQMOD. Simply feeding a quadrature DAC output to the IQMOD, the MOD provides a ~40dB sideband rejection without other baseband corrections.
I'm using the AD9125 DA to generate a sin waveform.Use a 4x Interpolation,DACCLKP 400MHZ 、REFCLKP 100MHZ the DCI CLOCK 100MHZ,
The AD9125 SPI configuration is as follows:
Are you using the on-chip PLL for the AD9125? You only need to provide either a DAC Clock OR a Reference clock (if you're using the on-chip PLL).
Could you send a screenshot of how you are setting up the ACE GUI and DPGDownloader?
Thanks a lot for the reply and I would try above suggestion.
Meanwhile I found the interfacing of ML605 board with AD9122 evaluation borad at following link:
Since AD9122 is…
Does AD9125 in a direct conversion (without Mixer+PLL) worked on this FM application controlled by FPGA?
We have a customer that is developing a similar solution but for Brazilian Market.
Unfortunately this is a very old part and the 1x delay information is not available. I estimate it would be about 10-15 DAC clock cycles. Is there any reason you are not using one of our newer products like the AD9125.
