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?
I'm having an unusually difficult time getting read/write activity to the SPI port on an AD9911 on a new PCB I'm bringing up. This part has a REFCLK of 50 Mhz and I can see a good SYNC CLOCK coming out. I have POWERDOWN tied to GND. I have programmable…
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…
