Part Number: ADS4449EVM Other Parts Discussed in Thread: ADS4449 Hi
I am developing the ADS4449 on my Xilinx FPGA board. The calibration result is not good enough. I found the ADS4449 work with TWS1400EVM. But it is out of service now. May you provide…
Part Number: ADS4449 Hi
I have three ADS4449 devices on the board (ADC1, ADC2, ADC3), using a total of 12 channels.
The data is transmitted from the HPC interface to the FPGA board.
I have observed some issues while capturing data with the FPGA…
Part Number: ADS4449 Tool/software: Hi TI team,
We are experiencing the intermittent toggle data measurement. For example one sample can be -2500(in raw unit), and the next sample is recorded is about 2530.
Please see the photo below for 1 second…
Part Number: ADS4449 Hi,
I am facing that there is no ADS4449 output signal at bit 1 and bit 2 while in test pattern mode . Please refer to the attachment for the two different phenomenon at ADS4449 output. Looks like there is no any signal applyed…
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 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 We are facing some noise issues when capturing signals using the ADS4449 with some analog front end circuit for an oscilloscope project. As per suggestion from TI customer support, I'm posting this query as we need help with this…
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
picture below is data_D…
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…
