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 suggestions…
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 Tx3…

For this function, their SW team needs to use ctypes.c_double for the parameters. We are assuming their team aware of this but wanted emphasize.
For example;
setPllLoFbNcoFreezeQec(fd, ctypes…

Allan Fan said: loopback without any signal. the noise floor is about -12dBm
This is a loopback setup without input signal and AFE Tx connect directly to the SA. So we thought the Rx input power should be no problem but don't know why output noise…
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…
Hi Kevin & Allan,
I replied our result in email to both E2E forum and here, since we had an email last time.
According to TI suggestions, I place TI APIs before our current JESD Status Check mechanism. As shown in picture, all error messages are literally…

Hello,
Could you please provide detailed reflow conditons for the AFE7799 ?
My customer has so far performed SMT on the AFE7799 with peak 250 degrees reflow condition.
Is this peak temperature the right temperature for the AFE7799…
