Hi,
can anybody help me figure out how to configure UAB as Mixer. In TRM it says it's possible and that's it.
I know it's all in changing registers, but I'm having problems as I don't know how to implement Mixer using
those components by comparing them to schematics I found on internet.
I'm using PSoC Analog Coprocessor (CY8CKIT-048),
You can see UAB structure on attached picture.

Hi,
Attached is the sample project for Downmixer. This project uses UAB based custom Component. PSoC Creator 3.3 CP3 (link below) to be used for testing the project.

Thanks,

kristijan,
This is schematic of a simple BPSK modulator / demodulator assembled from a simple Opamp or PGA with G=1. To perform correctly, the input signal needs to be centered across virtual analog ground (typically VDDA/2), then the output is also centered around it. When AMux switch is closed, the Modulator gain is -1, and when it is open the gain is +1. The AMux switch needs to be connected to the Virtual GND or simply to a capacitor (which will automatically average around the middle of the input signal). Such circuit can perform both like modulator or demodulator.
You can find detailed explanation of the modulator circuit operation here (approx at 14:00):
