With the advent of radioactive beams there is a quest for developing novel experimental methods and instruments able to cope with beam characteristics to extract spectroscopic information and to study novel nuclear reaction mechanisms. The tendency is towards Digital Pulse Shape Acquisition since it allows one to fully profit of the information encoded in the detector output response. Even if the convenience of driving the signals over differential pairs to preserve signal integrity in noise environment when long cables are used is evident, there is a lack of digitizing electronics that features a differential input. To this aim we designed, build and qualified an antialiasing module that provides 256 channel antialiasing filter with selectable parameters and differential input to be coupled with the GET – Generic Electronic System for TPCs - backend electronics. The contribution focuses on the board design, layout and performance measured both as a standalone circuit and during on-beam experiments.
