Hi Drew,
Thanks for your reply.
Yes, everything is readback correctly, so I am confusing what could be the possible reason causing this kind of issue.
Actually, I have made four boards, and total 12 ADS4449s(three on each) have this problem.
So from your…
Part Number: ADS4449 Other Parts Discussed in Thread: ADC08D1520 , How can I determine the maximum amount of jitter tolerable from my clock source? The datasheet just says to use a very low jitter clock source. I've looked at the ADC08D1520 which gives…

Part Number: ADS4449 Other Parts Discussed in Thread: ADS4149 I am setting registers 0xA9 and 0xAC on an ADS4449 to play with the CLOCKOUT DELAY settings. It seems to have zero effect on the data being received.
Is there any other setting that needs to…
Part Number: ADS4449 Hi,
I have a design problem
Parts:ADS4449IZCR.
After AD sampling, it enters FPGA and captures data
When no input signal or input DC = 0V, there are still some dataBit such as Bit_4 and Bit_5 fluctuate

Part Number: ADS4449 Other Parts Discussed in Thread: ADS42LB69 , Hi,
I am evaulating multi channels ADC. My application needs 12 channels ADC. If I choosed ADC like ADS42LB69 , the design will use 6 ADCs. But if ADS4449 , only 3 ADCs will be used.

Part Number: ADS4449 what is the maximum delay between the CLKOUTABM/P and CLKOUTCDM/P? i thought it was 300ps but i can find out the information if i want to use ads4449 pattern generator (especially ramp generator) for all channels, is there a way to…
Part Number: ADS4449
Hello,
What is the relationship between the analog input frequency and sample rate of ADS4449? I am a little confused about the below table, does the analog input frequency meet the Nyquist? What is the input clock frequency range…
