Part Number: DAC37J84 Other Parts Discussed in Thread: LMK04828 , , DAC38J84 Hi
We try to connect SYSERF SIGNAL between LMK04828 and DAC37J84 as LVPECL DC coupling connection which shows in DAC3XJ8XEVM-SCH_D SYSREF TERMINATION.
But we cannot understand…
Part Number: DAC37J84 I have a DAC37J84 running with Fs at 984MHz. I need to generate a 400Mhz carrier. I can do this just fine using the coarse mixer of the DAC with FS/2 (and inputting a carrier at -92MHz), but when I try to use the NCO it does not…
Part Number: DAC37J84 Other Parts Discussed in Thread: LMK04828 , TEST Hi team,
Could you please suggest me how to improve the NF?
My customer has tried the things below, but it was not effective:
- Add decoupling cap on VCC
- Stop inputting SYSREF after…
Part Number: DAC37J84
Hi,
I am using DAC37J84 custom board with NCO enabled bin file which gives me the output (at 50 Ohm termination load) as per the below mentioned figure.
As per the waveform the voltage swing is around 296mV peak to peak (single…
Part Number: DAC37J84 I am generating two 100 MHz signal from DAC37J84 EVM channel A and B and measuring these in an oscillioscope. As shown in the below figure, I (channel A from DAC) is in green and Q (channel B from DAC) is in blue.
There are certain…
Part Number: DAC37J84 I am using the DAC in 250 MHz BW with 4x interpolation with the speed limit options as highlighted in the image below-
1. If I use the small fraction delay FIR filter will it reduce the BW further?
2. Is there any frequency response…
Part Number: DAC37J84EVM Other Parts Discussed in Thread: TEST , DAC38J84 Hi,
I am experiencing the same problems described in this forum http://e2e.ti.com/support/data-converters/f/73/t/815771?DAC37J84EVM-DAC3XJ8X-GUI-v-1-2-Link-Configuration-Issue.
When…
Part Number: DAC37J84 I am interfacing DAC37J84 EVM with Xilinx ZCU102 Zynq board. I am seeing in chipscope that FPGA is sending "bcbc" characters for doing CGS. But DAC is not recognising "bcbc" characters and toggling SYNC accordingly.…
Part Number: DAC37J84 I used DAC37J84 EVM with Xilinx Zynq ZCU102 board. Below is my DAC configuration.
LMFS: 2441
DAC input rate: 250MSPS
Lane rate: 10Gbps
Interpolation: 4x
I observed that if I set K = 5 or 10 or 20 or 28, I am getting output.
For each…
