Hi Neeraj,
Here are some waveform drawings illustrating how my FPGA design is driving the DAC3171. One includes the constrained timing of the signals, and one includes the relationship between DATACLK, SYNC, and DATA[13:0].
Does anything appear off…
Part Number: DAC3171 Other Parts Discussed in Thread: DAC3174 I am struggling to get any passing results from the built-in iotest feature of the DAC3171. Additionally, there is some odd behavior in config5 register (addr 0x05) that I cannot reconcile…
Part Number: DAC3171 Hi，
I’m using DAC3171 in 7-bit mode，but finding that the lower 7 bits seems not showed because the noise floor is much higher. I think DAC3171 does not work in the 7-bit mode properly.
and I have found that the Bit 6 of config5…

Dears：
Could you kindly help to check the schematic and parameters, since we use our DAC3171 to replac ADI's AD9743, there is some issue about our design:
1. DAC3171's Parameters: …

I'm using DAC3171 7-bit DDR mode, but it seems like does not work in that mode.
My setting is
reg 0----0x46fc
reg 1---0x600e
reg 2---0x3f80
reg 3---0x0001
Is it right?
Part Number: DAC3171 Hi,
in my current design, I'm using DAC3171.
I see some spurs when TX with the DAC
when I checked my Layout I saw that there are some differences between what I did and what is shown in the EVM layout
I wish to understand if…
Hi CoolDog
Have you resolve the spurious response issue?
I reviewed your information again and noticed that you are using a similar schematic to the DAC3171EVM, but are using the DAC in 7-bit mode.
When enabled in that mode the FIFO input clock is on…
Part Number: DAC3171 Other Parts Discussed in Thread: DAC3174 Hi,
For my design, I need to have a DC coupled DAC3171, interfacing it with an OPAMP to have a differential to single ended output. I have been reading the application report sbaa135 which…
Hello,
We also had to order more DAC3171. Earlier this year, we were told from to order direct from the TI store to ensure the correct part is received. We have done so, and TI passed our order on to DigiKey for fulfillment. DigiKey was the distributor…
Part Number: DAC3171 Hi Team,
Customer wants to know about DAC3171 layout.
Do we intend to leave a keep-out area in the thermal pad like below? Or it is okay to ground the entire thermal pad?
Thanks!
Andrew
