The DRS4 chip is a full custom Integrated Circuit developed at PSI, Switzerland. It contains a switched capacitor array (SCA) with 1024 cells, capable of digitizing eight analog signals with high speed (6 GSPS) and high accuracy (11.5 bit SNR) on a single chip. This web site contains the chip documentation and software (firmware, drivers, applications) needed in order to work with the chip or the chip evaluation board.

This is software that is only useful if you also get the hardware for it.
