Part Number: DAC39J84 Hi
We are using DAC39J84 chips in developing our own mezzanine products. We are running into issues, where we can't communicate with DAC chip via SPI lines. We had almost 40 boards out of which more than half have the same issue…
Part Number: DAC39J84 Other Parts Discussed in Thread: DAC39J82 Tool/software: Hello TI support,
In the DAC3XJ8X GUI we see Link Configuration errors.
Our current FW scheme is the following:
We are using two of the TI JESD204 cores,…
Part Number: DAC39J84 Hello,
We have built several prototypes (30) using the DAC39J84 device. Some of the boards seem to work properly, but 1/2 of the boards have lane errors. This is a simple FMC card, the diff pairs are relatively short from the FMC…
Part Number: DAC39J84 Hi there,
There is a term "complex bandwidth (BW)" in Table 11 of DAC39J84 datasheet (SLASE48A).
In our case, we have DAC39J84 running at 1 GSPS (without interpolation). Therefore, the analog bandwidth is 500 MHz in our system…
Part Number: DAC39J84 Tool/software: Hello,
We are facing a problem with the DAC39J84 seemingly not recognizing K-symbols from the TI JESD IP core.
Here is what we see in the TI GUI:
Here is the value of all the registers of the DAC…
Part Number: DAC39J84 hello,
Is the data in the IBIS file required to match net length when running the JESD interface at 10 or 12Ghz? or is it sufficient to equalize just the traces to the DAC39J84 device from an FMC connector?
(ie will the JESD…
Part Number: DAC39J84 Other Parts Discussed in Thread: DAC38J84 On the TI website, under information for this part (DAC39J84), the ibis file is for another device (DAC38J84). Is this an error, or is the ibis file the same for the 2 devices (DAC39J84 and…

Hello Support !
I'm trying to use the boundary-scan on the DAC39J84, but once the TAP set ins sample mode, the DAC stop sending data (see logic analyzer result below).
I'm able the set the tap in BYPASS or IDCODE mode and get…

I want the DAC39J84 output converted to single ended SMA connector.
On the datasheet sec 7.3.28 and 7.3.29, it give two simple circuit for the DAC output single ended.
But on the evaluation board, it is using a 75 ohm balun…

Dear all,
I'm struggling with the configuration of the DAC39J84.
I do not see any outputs from the DAC due to errors on the lanes. Even if I'm able to perform the NCO test and the PRBS…
