The main FEROM (Front End Read Out Module) task is the digitalization of the 2.6 million SSD (Silicon Strip Detector) strip values in 160 µs.This is achieved by digitizing in parallel the 1698 double-sided SSD module signals (each containing 1536 strip values).The FEROM also performs the zero-suppression and offset correction, the event-data derandomization using Multiple Event Buffers (MEB) and the event data transfer to the DAQ.
