Part Number: ADS54J66 Hi team,
One of our customer's issues, I'm forwarding it below, could you please provide some troubleshooting suggestions
I am using ADS54j66 ADC on my board, and I have met some questions.
1. I want to use DDC mode 8, my…
Part Number: ADS54J66 Thanks for your answers. Regarding answer #4 “The rails were swapped to make the PCB routing easier by removing crisscrossing that would have forced us to use multiple layers”, if the rails are swapped, wouldn’t it change the input…
Part Number: ADS54J66 Other Parts Discussed in Thread: LMH6401 , LMH3401 Hi,
I am now designing a new board and I want to use the ADS54J66 device. I have few questions regarding it. For some of the questions that I am raising is due to many Q&A that I…
Part Number: ADS54J66 Hi, I am using ADS54j66 ADC. I have an requirement multi chip synchronization. it was achieved by JESD204b subclass 1. two adc's are mounted in the board. Following are JESD204B parameters. No of lanes L = 4 No of convertors M = …
Part Number: ADS54J66 Hi,
In the process of using ADS54J66, we found that some of the ADCs we used failed to be configured under certain Chip temperature ranges, such 30 to 40 degrees Celsius. As shown in the picture below, channel AB (some AdCs are channel…
Part Number: ADS54J66 Other Parts Discussed in Thread: LMH6553 Dear TI support team,
I have a few questions regarding the use of the ADS54J66 that I hope you can help with:
Datasheet page 24 says: "The common-mode voltage of the signal inputs is internally…
Part Number: ADS54J66 Other Parts Discussed in Thread: ADS7957 I would like to know how critical the cap across the reference voltage pins (REFP/REFM) is toward the performance of this device? The recommendation is 10uF, would the use of a 4.7uf be adequate…
Part Number: ADS54J66 Hi
Nominal value of analog input is mentioned as 1.9V.Absolute ratings from -0.3V to 3V.
What is the recommended minimum to maximum voltage level at analog inputs ?
Thanks in advance
Part Number: ADS54J66 Hi,
I've been seeing data from a single ADC where the bottom 5-bits are always 1s. Attached is a screenshot of data readout from two different ADCs, one ADC has this stuck-bits issue and the other is fine. You can see the sine-wave…
Part Number: ADS54J66 Other Parts Discussed in Thread: LMK04828 Hello Every One,
I am planning to use ADS54J66 ADC for the input Frequency of 650MHz to 700MHz range.
I have not seen SNR and SFDR performance in Datasheet for that frequency.
I referred…
