Part Number: DAC38RF97 Other Parts Discussed in Thread: LMK04828 We are using this DAC38RF97 part in our radio project. Our design mainly based on the TI's reference design. We are having problem of NO OUTPUT. We have checked all voltages and they are…
Part Number: DAC38RF97 I'm using the DAC38RF97 on a custom PCB with 20x interpolation.
Here are some details of the configuration:
100MHz reference clock (single ended)
DAC PLL output freq = 6400MHz (locks with an LF=3)
JESD mode: 42111
Interp…
This is not the problem. It appears that the SPI bus cannot handle 3 bytes of data... but rather we need to have a continuous clock of 24 bits. This was implemented in the FPGA and fixed the problem. The multi-millisecond clock pause, I believe, is the…
Part Number: LMK04828 Other Parts Discussed in Thread: DAC38RF97 I use LMK04828 SDCLKOUT for DAC38RF97's and FPGA Artix-7's SYSREF. At the FPGA side, LVDS_25 bank is used, where there are internal 100ohms termination resistors but no bias. In the reference…
Hi Xlaodie, please see my comments below.
XIaodie Hu said: Combined with TSW14J57EVM, I only use the "on-board VCXO clock mode" of DAC38RF82EVM. What is the frequency range of sinusoidal signals generated by DAC38RF82EVM?
The frequency range which…
Hi Jonathan,
This is an error in the GUI. It should be possible to select 16x interpolation for the mode you are trying to use.
Can you replace the following file with the one attached: modes_n_clock_programming.tx t
The file can be found in C…
