View ArticleRe: ADIS16201 - Output data rate? - Alternatives with wide bandwidth?
With respect to the LSB weight, what is driving that requirement for you? Is that influenced by noise? If you are running this product at its maximum ODR, we can project the total noise to be...

I'm working on a software-defined radio design based on the combination of the Analog Devices AD9361 and Zynq SoC. In our design, the stream of data received from the AD9361 is broken up into logical...

It has been a while since I looked at this but I believe the app-note equation is how to calculate the best/recommended value for RFB while the equations above are MIN and MAX limits for RFB that the...
View ArticleRe: Question about the "CopyFloat2Fix" and the "CopyFix2Float" function
Hi Liang, In the SigmaStudio for SHARC application, the CODEC is configured to receive the sample in the lower bits. That's why you need to shift up before converting to float. Best Regards,John

Hi JoeB, HMC series negative bias switches inclusive of HMC547LP3 allow operation at vey low frequencies near DC but they are not suitable for true-DC operation. The RF line potential should be within...
View ArticleRe: Delay definition and performace of the ADF4112 software tool
Page 21 of the ADF4112 explains what the DLY and SYNC bits do. When DLY = 1, the prescaler output is resynchronized with a delayed version of the RF input. This can reduce total phase noise by reducing...
View ArticleRe: Serialization with axi_ad9122.
Until now what i checked on the axi_ad9122 code is that when the SERDES DDR N parameter is 0 the IP will take just the 16 LSB of each 64 bit data input ( dac_ddata_0 and dac_ddata_0) and will give at...

Hello Yang, Try this sequence to disable the CRC and see if it works. 0x00 0xFD 0x00 0x00 0x01 0x33 0x07 Then try to read or write to the registers. Thanks Rajeev

The IP is designed to support that frequency- but with the modifications you made- I don't think it will. You are probably keeping the MMCM and its parameters same. You need to check the requirements...

Yes I didn't set the MMCM parameter to 0. I will set it to 0 and I will check what will happen. What if I keep the MMCM but change the parameters value!? Can you give me an insight about parameters...
