Highly segmented digital tracking calorimeters consist of multiple layers of high-granularity pixel detector CMOS sensors and absorption/conversion layers. Two separate prototypes are being developed: (1) an electromagnetic calorimeter for a proposed ALICE upgrade (during Long Shutdown 3) and (2) a hadronic calorimeter for medical proton computed tomography imaging. These prototypes employ the ALPIDE detector chip developed for the ALICE Inner Tracking System. The ALPIDE chips are mounted on intermediate aluminum/polyimide flexible circuits with ultrasonic welding. This contribution presents findings and solutions to the challenging design of high-speed readout electronics with efficient use of FPGA resources for these prototypes.
