This contribution aims to present the technological developments which are been carried out in the frame of the data acquisition systems for the EXOGAM2/NEDA and AGATA nuclear physics experiments. For EXOGAM2/NEDA detector, we present a 14 bit, 200 Msps, 4-differential channel digitizer mezzanine card. The bandwidth of each channel is 30 MHz and the noise level is σ <1.5 LSB with and ENOB greater than 11. It includes a SPI protocol to remotely control the baseline for each channel independently. Four of these mezzanines can be housed in a NIM format card to conform a 16 channel low noise and high resolution DAQ system. The mezzanine can be easily controlled using an FPGA. The other development presented is a control board module for the 12-channel digitizers boards of the AGATA gamma spectrometer. This module implements a virtual cable system via fiber optics for the execution of remote operations coming from the preprocessing system and controls the digitizers boards using an adhoc backplane. A set of 4 digitizer boards plus one control board can be housed in an standard mechanic setup and three of this boxes can be allocated in a standard 19-inches 3U subrack, giving a total of up to 144 channel digitizer compact system. Both designs have been carried out with a cost-reduction and reusability principle as several other nuclear experiments could take profit of them with none or little modification. Emphasis will be put on these aspects of cost reduction in comparison to previous developments and the possibilities of using these developments in other present or near-future systems. Forecasts of greater integration plans of these systems will also be presented.
