Tool/software:
Hello
I had success bringing up the "TI ZCU102 8b10b" project, ZCU102_AFE79xx_8b10b_10Gbps, using the AFE7950EVM connected to the Xilinx ZCU102 development board. In this reference project there are 8 lanes
This project using the following settings:
- fpgaRefClk = 122.88
- FRef = 491.52
- FadcRx = 2949.12
- FadcFb = 2949.12
- Fdac = 2949.12*4
- LMFSHd = 44210
- K = 32
- LvdsSync = False
I follow the TI204c-Setup.docx:
- Power on ZCU102
- Power on AFE7950EVM
- Open Latte
- Run setup.py
- Run devInit.py
- Run ConfigLmk.py
- Program FPGA
- Release master_reset_n -> 1
- Release tx_reset -> 0
- Run ConfigAfe.py
- Release rx_reset -> 0
I modified some IP/file properly to be compliant to my goal, like GT and PLL, jesd_link_params.vh file and the constraints.xdc file. My goal are the following:
- fpgaRefClk = 245.76
- FRef = 245.76
- FadcRx = 2457.6
- FadcFb = 2457.6
- Fdac = 2457.6*4
- LMFSHd = 24410
- K = 16
- LvdsSync = False
I change the GT config:
I change the PLL config:
I change the jesd parameters in jesd_link_params.vh:
I change the constraints file:
I see the IQ mapping in the refdesign_tx.sv is the following:
For 64bit mapping LMFSHd = 24410 this IQ mapping must be change?
In which file can be found the IQ mapping table?
