Part Number: DAC39J82 Other Parts Discussed in Thread: DAC38J82 Tool/software: Title: Issue with DAC39J82 Operation Beyond 2G Sampling Rate
Post:
Hello, We have designed a custom board with the DAC39J82 and are encountering an issue where the DAC…
Part Number: DAC39J82 this is use 2x interpolation generate frequency spectrum:
this is use 1x interpolation generate frequency spectrum:
Why are they so different? How do I set up the register so that the frequency spectrum can be normal for 2x interpolation…

Part Number: DAC39J82 Other Parts Discussed in Thread: LMK04828 HI
i use a DAC39J82 , LMFS=4211,the config:
but the JESD204B NOT LINK, the sync always re-link:
the config register 0x64~0x7 data was 0x0509,the bit config :
what should i do what to solve…
Part Number: DAC39J82 Other Parts Discussed in Thread: DAC38J84 I am looking for the BSDL file for the DAC39J82. I have the BSDL for the DAC38J84, but its not the same.
Part Number: DAC39J82 Other Parts Discussed in Thread: LMK04832 Hi,
We have used DAC39J82 and LMK04832 in our design. Need the layout of it reviewed by TI for any feedback. Can you send a private email so that we could share the layout files?
Arunkumar,
See attached for vendor stackup used on this board. For your other question, the 19 mil traces are loosely coupled at 50 Ohms single-ended and the 9 mil traces are 100 Ohm differential coupled traces.
Regards,
Jim

Part Number: DAC39J82 Other Parts Discussed in Thread: DAC5687 , I have used the DAC5687 and was able to phase align multiple chips via the PHSTR input.
How do I phase align the outputs of multiple DAC39J82, to ensure they always come up with same phase…
Part Number: DAC39J82 Other Parts Discussed in Thread: AFE7444 Hi,
There are three DACs used in our design. All three operate at different sampling and update rate.
Will there be any impact on performance if the power rails are shared? Example: Powering…
Part Number: DAC39J82 I sort of understand the answer to time syncing several DAC39J82 together, which I will incorporate. I'm using the NCO and need to ensure each NCO in multiple chips come up at the same phase relative to each other. The syncing ensures…
