The chip can accept trigger rates up to 1.1 MHz to perform a dead-timeless readout within 900 ns per trigger. For testability and calibration purposes, a charge injector with adjustable pulse height is implemented. The bias settings and various other parameters can be controlled via a standard I²C -interface. The chip is radiation hardened to an accumulated dose of more than 100 Mrad. Robustness against single event upset is achieved by redundant logic.
