Requirement : generation of frequency from 120 to 230 MHz with min 100Hz step size.
Will AD9911 be sufficient for that?
what is frequency resolution for AD9911 in Hz?
Hi,
I use AD9911 in my design. we have LVPECL driver to drive differential clock to REF_CLK+/- of AD9911. I want to add Thevenin termination at AD9911. But I found in the datasheet of AD9911, it says Reference clock in first mode (logic low), ".. must…

thank you for your reply
However, even if I is 0 DFRRW in the sweep does not stop?
Do you have an answer

Hello, I am working on the AD9911 with a DSP. In the control line, I found this device do not have a pin I/O_RESET as in AD9910, and I confused with use of reseting device.
Does this pin MASTER_RESET must be connect out and be used? When starting up…
Unfortunately no. The AD9911 eval software does not operate on either Win7 or Win8.
v5.3 - Corrected AD9911, AD9958, and AD9959 to show they do include an OOK
Hello all,
I’m trying to realize amplitude modulation on the DDS AD9911. But I do something wrong. For example, I want to implement 2-Level Modulation without RU/RD. I write to the DDS:
CSR - 0x22
FR1 - 0x00,0x00,0x00
CFR - 0x40,0x03,0x03
CTW0 …
I have purchased a AD991 Evalboard. With it came software and drivers. I'm working on a project where I need to use the function multi tone modulation, but the only functions included is Spur reduction mode and Test tone modulation. Have I missed something…
The enable EEPROM jumper for the AD9911 evaluation board is W9.
Best regards,
Mark
