Hi Sukhdeep, If you have downloaded the GUI from the product webpage, then this is the latest GUI version. I am assuming you have done that, correct? Next, I would directly connect the USB cable from...

Hi Benjamin, Thank you for your post. I think it makes sense to reverse the filter component order as you drew it. Primarily, these components serve to limit the DC current which may flow into the...

Hello Madhumohan, Thank you for your post. Have you tried using a function generator or other signal source with a smaller amplitude, such as the internal square wave test signal? Regards, Ryan
View ArticleForum Post: RE: ADS7057: Conversion Time and Falling Edges
Thank, will keep this in mind. Another question: I see in the datasheet a calibration needs to be completed after a power cycle. Is this a power cycle of bother rails? Just AVDD? Just DVDD? Either?

Hello Patrick, Thank you for your post. The schematic looks mostly correct! Just a couple comments: I believe there is just a typo in the net names for LA and RA following the low-pass filters. Should...

Hi Bogdan-Mihail, Thank you for your post. Cross-talk can be reduced using clean layout techniques. As you can see, there is quite a bit of overshoot on the SPI signals, especially SCLK. A smaller...

Hi Saeed, Thank you for your post. Are you measuring AVDD and AVSS current in the same direction with respect to the ADS1299? I would expect the supply current to be equal and opposite polarity for...

Hello Mitsuo, Yes this line rate is valid you have calculated it correctly. Yes this means you can operate the ADC JESD link in subclass 0 (without sysref) with an FPGA receiver in subclass 0. Best,...

Hi David, If both ADC PLLs are getting phase locked signals then each sampling clock generated by the internal PLLs will be aligned to each other. Now this is the ideal case where there is no routing...

Hi Ryan, thank you very much for your clarification! That helps. I have another question about actively shielded channel wires, using the RLD signal. Does it make more sense if I open a new question...

This device uses AVDD as its main power source, and DVDD serves to set the logic level, so the suggestion is in the case of a power cycle on AVDD. Regards, Joel
View ArticleForum Post: RE: ADS127L11: DRDY-pin is not getting low
Hello Iouri, That is good news that the ADC is working correctly after power-up. Looking at your timing waveforms, you are using the wrong SPI mode. The SCLK must idle low, not high. SCLK should be...

Hi Zaheer Hashim, Common-mode chokes are good for filtering out high frequency noise on the inputs. So yes you can use them, but you do not need to add them. That feels like a question you need to...
View ArticleForum Post: RE: ADC12QJ800: Bypass SYSREF windowing for low CLK freqs
Hi David, The calibration does not change the setup and hold requirements, it simply helps align sysref to the clock that is sampling it. The datasheet does not specify the exact setup and hold as it...

Hi Mark, Does the GUI not move past the loading window? The GUI should still load without a connection to the EVM, it should just display a pop-up that prompts going into simulation mode. Thanks.
