Output (TX)

Its the sum of both I and Q. You need to convert the TX differential output into single ended by using a Balun as shown in the reference EVB schematic.

Its the sum of both I and Q. You need to convert the TX differential output into single ended by using a Balun as shown in the reference EVB schematic.

Thank you for your answers. I have a few additional questions:

1. Are the signals at points 1 and 2 the I and Q components, respectively, or is it the opposite?

2. Are the signals at points A and B identical?

3. How do the signals at A and B become TX2+ and TX2−? In other words, how are they converted into differential signals?

4. Is there a phase difference between the output signals TX2+ and TX2−? If so, is the phase difference 180 degrees?

Please refer to UG-1727 for more details. The differential TX output is analog domain, which means 180 degree difference. The I and Q paths are combined using IQ mixer.

Thank you very much for your responses and support. We really appreciate your help.

We have studied UG-1727 in detail; however, we still have a few questions:

1. Is the signal at point 1 SERDINAB+ or SERDINAB−? Is this configurable?

2. Is the signal at point 3 obtained by multiplying the signal at point 2 with a cosine waveform or a sine waveform? Is this configurable?

Thank you in advance for your time and clarification.

1A) Yes, this is configurable. I guess you are asking about swapping P and N. You can change in the profile.

If there is a PN swap, make the below highlighted parameter 1 in the JSON.

2A) It does not matter. you can not configure it.
