High-speed multichannel ADCs are costly and require complex FPGA or MCU firmware to communicate with them. The Multi-Voltage Thresholding (MVT) approach can replace to some extent an external ADC by harnessing the internal FPGA resources, thus reducing costs and complexity. The MVT approach needs only a few low-cost external components. The focus of the contribution is presenting an open-source IP-Core that implements the MVT approach and simplifies its implementation on a standard FPGA. The contribution also provides an overview of characterization measurements and specific calibration method. Our example application demonstrates the viability of the developed IP-Core for signal acquisition from multiple SiPMs.
