In the past, the longitudinal multibunch feedback (MBFB) at the Swiss Light Source (SLS) storage ring has used an analog upconverter to translate the output signal of a 500 MSample/s DAC to the 1.25-1.5 GHz operation frequency range of the longitudinal MBFB kicker and its power amplifier. For SLS 2.0, we have investigated the possibility of driving the power amplifier of a newly designed kicker (operating at 1.75-2 GHz) directly with the multi-GHz/multi-GSample/s DACs of an RF System-on-Chip (RFSoC). We present test results with the new SLS 2.0 kicker magnet and its power amplifier. Related methods for RFSoC-based bunch-to-bunch crosstalk compensation in the presence of transient beam loading (due to the superconducting 3^rd harmonic cavity in the storage ring) and 200 ps range arrival time variations along the bunch train are also presented. Moreover, the latest status and plans for our MBFB firmware/software implementation on an RFSoC will be given.
