@Benathon@blind_via you can also place a 100 ohm resistor and the differential signal next to the chip where you need to use the single-ended signal, connect the differential pair to both ends of the resistor, then connect the differential pair + to the input, and ground the differential pair -.
@Benathon@blind_via When you need a single-ended signal at the chip, use a differential signal and a balun next to the chip. Connect the differential pair to the balun, and then connect the balun's single-ended output to the input.
