High Speed DISB electronics

The M-DISB-191 is a high speed electronics board designed around the MIPI (Mobile Industry Processor Interface) communication protocol and the Hamamatsu S17122 linear CMOS detector. The M-DISB-191 offers a feature rich FPGA based platform that allows for full control of the 2048 pixel S17122 detector with line rates up to 61 kHz (for 2048 pixels) and additional functionality including on-board wavelength calibration coefficients, configurable well depth and HSYNC/VSYNC external triggering, making it an ideal choice for applications such Optical Coherence Tomography (OCT).
