Part Number: AFE7799 Tool/software: Hi,
Our TI store inventory and pricing API status is active, but when we tested the sample part AFE7799 from the API documentation, it gives us the error
"keymanagement.service.InvalidAPICallAsNoApiProductMatchFound…
Part Number: AFE7799 Tool/software: Hi Expert,
The JESD receiver should generate synchronization request by asserting SYNC~ signal.
In our RU system, we don't see the AFE7799 assert SYNC~ signal when initialization, and our FPGA asserts SYNC~ when…

Hi Experts
We have issued the uplink DC spur problem previously, and got the suggestion to use the function "rxDcBw()" for improving the performance.
We have tried the dcFilterBwWord from 17 to 22, but it got…
Part Number: AFE7799 Hi expert,
Below is the ACLR test on Tx3 and Tx4 channel from customer. They used FPGA for DPD. The HW circuit design on each channel are the same, but ACLR result is different.
The yellow waveform in the figure is connected on…
Part Number: AFE7799 Hi,
We can now use setPllLoFbNcoFreezeQec() to change the frequency, but we meet an issue. After changing the frequency, the power at the center frequency would become larger. It appears to affect DPD operations. Do you have any…
Part Number: AFE7799 HI expert,
Customer used AFE7799 and see an undesired spur on the SA when measuring Rx EVM and CRC. The setup is like below figure.
When data is on the carrier, the spur would cause CRC fail.
May we know what might be possible…
Part Number: AFE7799 Other Parts Discussed in Thread: AFE7769 Hi expert,
Is it correct to use commend setPllLoFbNcoFreezeQec to change frequency?
Could you please explain for the parameter and how to use them?
setPllLoFbNcoFreezeQec(int fd, double…

Dear Kang:
Dear Allan:
Today we test Alpha_EVM_bringup.py and loopback.py at two kinds of HW platform. Alpha_EVM_bringup.py has “AttributeError: 'NoneType' object has no attribute 'Reconnect'” issue. And loopback.py happen may serdes sync error. Please…
