I am using AD9625, when I use 4 lanes 1GSPS, it is normal, however when I use 8 Lanes 2.4Gsps, FPGA shows that it could not lock.
Could you please help check above issue.
What's the meaning of CTAT voltage, what's the relationship between CTAT voltage and temperature.
My design is four AD9625 chips working at 2.4GHz sampling frequency, the clock is provided by a HMC7044 chip. After sampling the data sent to the FPGA, AD9625 TX JESD204B protocol configuration for the 8 LANES, F = 1, K = 32, Scrambling. The FPGA…
What is the full scale analog input required for AD9625 in EVAL-AD9625 at J301?
Thanks for explaining the flash routine.
So far, we can pinpoint the error to the message related to the AD9625 not being recognized by the SPI routine.
Our board goes like:
ad9467 spi32766.0: Unrecognized CHIP_ID 0xFF
And a working…
1) The evaluation board for AD9625 does have support for 3.3V on DVDD_IO & SPI_DVDD_IO. The datasheet for AD9625 will only specify 2.4 to 2.6V for these domains. The 3.3V support may be added in the future, but will not be reflected in…
I have some questions with AD9625, We set the sample clock at 2.4GHz with AD9516 and ADCLK948, but the ad9625
cannot work correctly, the rx_sync and rx_tvalid go low always . we measure the swing of sample clock, it is 1100mv VPP at the source…
Yesterday, I answered some frequently asked questions on a new 2.0GSPS 12b ADC, AD9625, that was recently released.
As with many GHz ADCs, there are typical questions by system designers about the operation and performance of the ADC. Today, I have…
In our application we want to use two AD9625 devices to digitize the IQ baseband output of an analog quadrature demodulator and enable the decimation filters on the AD9625 to reduce the amount of data transferred over the JESD204B interface as there are…
When you go on the Analog Devices website under AD9625 and click on ‘Evaluation Boards & Kits’ then click on ‘AD9625 Evaluation Board Documentation (Wiki Site)’ then click on ‘BOM’ you end up getting the artwork in the zip file (not the BOM).…
