Hi Gulla,
I've just over-rided my DAC settings using your SPI configuration sequence and I see that the outputs are as expected . I believe the issue to be on your FPGA side and not the DAC side. Have you been able to test with swapping the DAC A and…
Part Number: DAC38RF80 Hello,
I am trying to understand the operation of the NCO in a DAC38RF80 as shown in Figure 66 on document SLASEA3C,
1) What is the mapping between the 48 bit accumulator output and the 16 bits used to index into the lookup table…
Part Number: AFE7950EVM Other Parts Discussed in Thread: TEST2 , DAC38RF80 , AFE7950
Hello,
I am using the AFE9750-TRF1208-EVM in conjunction with the TSW14J56.
I would like to know if it is possible to configure the DACs to generate a constant output value…
Part Number: DAC38RF80 I will use DAC38RF80 for my project.
I read (8.3.19), (8.5.39) and (8.5.40) on dac38rf80.pdf, so I have a few question.
I want to know the maximum and minimum gain values when I control these registers.
In Table56, when asserted…
Part Number: DAC38RF80 Other Parts Discussed in Thread: TSW40RF80EVM , Hello all,
I am using the TSW40RF80EVM to evaluate the DAC38RF80. I will be using the DAC to drive a variable load (across the entire Nyquist range of the DAC) where the impedance is not…
Part Number: DAC38RF80 Hello,
For the DAC38RF80, can I use one JESD204B link to drive the both Multi-band DUC Channels with the same I/Q data. Multi-band DUC Channel 1 will drive DAC A, and Multi-band DUC Channel 2 will drive DAC B. The channels will…
Hi Kang-san,
Thank you so much for your kind measurement! Now I'm more confident that DAC38RF80 shouldn't be the cause.
Could you please let me know the tone frequency you checked? Did you check it with 3.5GHz single tone?
The customer checked SPIDAC…
Part Number: DAC38RF80 Other Parts Discussed in Thread: , LMK04832 I am using dac38rf80 and I am getting JESD alarms on registers 0x64 to 0x6b as 0x2000.
1. In which scenario link configuration error will be set by dac and how to resolve this alarms.…
Hello Renan,
The ADC32RF80 and DAC38RF80 on the TSW40RF80 cannot support flexible, programmable FIR DDC, DUC filtering, resectively. The FIR on the ADC32RF80 and DAC38RF80 are fixed and hardcoded. The customer will have to design their own RTL code on…
Part Number: DAC38RF80 Other Parts Discussed in Thread: DAC38RF82 We are planning to use multiple DAC38RF80. I've read thru datasheet sections 8.3.9, 8.3.10 on the multi-Device synchronization. How does that work when the DUC and internal DAC clock…
