Other Parts Discussed in Thread: DAC34SH84
Tool/software:
Hello TI team,
I am working on a custom design using the ADC3444 and DAC34SH84, both connected through an FMC card to FPGA. My goal is to implement the following data flow:
-
Acquire data from the ADC3444 and transmit it to the Processing System (PS) side.
-
Store the captured ADC data temporarily in ps DDR.
- Later, retrieve the data from storage and send it to the DAC34SH84 .
Since the ADC3444 outputs 14-bit samples and the DAC34SH84 expects 16-bit input, I need to pad the 14-bit ADC data to 16-bit before sending it to the DAC.
I have a few questions:
- How can i transmit the data from the adc to PS side ?Could you please provide system-level block diagram for this setup?
- What is the recommended approach for padding the 14-bit ADC data to 16-bit? Should I pad with zeros in the LSBs or MSBs to maintain signal integrity and dynamic range?
- Are there any available reference designs (for either ADC3444 or DAC34SH84) that illustrate a complete data flow from ADC to DAC via the PS
- Is there any specific initialization/configuration sequence I should follow for synchronizing both devices when routing data through PS?Attached the adc3444 and dac34sh84 datasheet link below
