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…
Part Number: DAC39J84 Other Parts Discussed in Thread: LMK04828 Hi there,
I have multiple DAC39J84 ICs to be synchronized. Each DAC39J84 is clocked by an LMK04828.
In a related thread , ±1 VCO cycle error for LMKs' output device clock aligning was found…
Part Number: DAC39J84 Are there any pullup or pulldown requirements for the jtag interface? In the evaluation board package it does not show any aside from the TRST needing a pulldown when JTAG is not in use.
Part Number: DAC39J84 Can the DAC3XJ8X family output a test tone, independent of a functioning JESD interface? Assume it is given a reference clock, and the it 's internal PLL is programmed as needed. Can I output a tone using coarse N*Fs/8 or the…
Part Number: TSW14J57EVM Other Parts Discussed in Thread: DAC39J84EVM Hi
As part of my learning I am using DAC39J84EVM and TSW14J57EVM to establish the JESD204B data transfer from Host side to the output of the DAC. As part of it, I would also like to…
Part Number: DAC39J84 Hi there,
I implemented the 2x interpolation on DAC39J84, which gives me a better looking spectrum and pushes the image frequency away.
In my case, with 2x interpolation, the DAC output sample rate (f_DAC) is 2 GHz. The input…
Hi Jim
Good news - it looks like we have a resolution for this. It seems that there was an issue in the HDL that meant the reset pin corresponding to RESETB was mapped somewhere else, and when I thought we were actually toggling RESETB, it was not toggling…
Part Number: DAC39J84 Other Parts Discussed in Thread: LMK04828
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…
Part Number: DAC39J84 Hi Experts,
We have this query from Cx about erroneous register map shown in SLASE48A .
Looking at D/S of DAC39J84, the addresses in Table 30 do not correspond to their matching descriptions as shown in subsequent sections. In particular…
Part Number: TI-JESD204-IP Other Parts Discussed in Thread: DAC39J84 Hi, I downloaded TI-JESD204B IP and use zc706_8b10b ref design for VC707 fpga board and DAC39j84. I use LMFS=8411 and HD=1. Here are few questions that bug me during my implementation…
