hi,
i am not aware on an issue with commonly available FPGAs where the termiantion resistors would be off by such a large amount. Your experiment with external termination with the internal termination disabled is what i would have done. The only other…
Other Parts Discussed in Thread: ADS54RF63 Hello,
I want to interface ADS54rf63 EVM with Virtex - 6 FPGA board using a FMC connector. I am very new in this field. am facing problem in making the .ucf file. please provide the relevant reading material…
Other Parts Discussed in Thread: ADS5444 , ADS54RF63 , ADS5440 , ADS5474 The ADS54RF63 datasheet states it is Pin-Similar/ Compatible to 12-, 13-, and 14-Bit ADS5440/ ADS5444/ ADS5474. However, it does not state how the NC pins 47,48,49,50 behave. In…
It is unclear whether the proper LVDS data pattern is being used for the ADC to DAC interface. If this is not set-up correctly with the prper interposer (FPGA, buffer, etc.) then the output pattern will not be proper. You can double check the interface…
Hi,
Take a look at the Application Note http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=slaa545&fileType=pdf where we have an ADC EVM connected to an FPGA development platform as well as a DAC EVM to the same platform, doing…
I'm interested in ADS54RF63-ADX4 evaluation board, but I cannot really tell if it support to export digital output raw data without time interleaved calibration from its user's guide. Could any one who has used this board help me out? Thanks.
Other Parts Discussed in Thread: CDCE62005 , DAC34SH84 Hello!
Even though there are posts related to this topic and read them, not able to figure out what is the problem is my setup.
What I have been doing is as follows
1. Giving a input signal…
Other Parts Discussed in Thread: ADS54RF63EVM Hi,
Whilst reading this post http://e2e.ti.com/support/data_converters/high_speed_data_converters/f/68/t/47555.aspx?PageIndex=2 I saw that you have some example VHDL for a different ADC. I am trying…
Rick,
In the EVM we have ETC1-1-13 transmission line transformer with impedance ratio 1:1, it does convert single ended signal into differential signal for ADS5463 analog input. ADS5463 has internal buffer at the analog input with 1 kohm differential…
Part Number: ADC083000 Other Parts Discussed in Thread: ADS54RF63 , ADC08D1520 , , ADC12QJ1600 Hello -
We are designing a ADC unit that requires a very wide full power bandwidth. We are considering the ADC083000, ADC08d1520 or the ADS54RF63. In our…
