Optional buffering and digital trigger daughter board. This is a daughter board of the front-end board. The analog block is wholly implemented on the analog daughter board. The FADCs are implemented directly on the Front-end board. However, a subset of these signals can be implemented on the Front-end board.
Figure shows the position of the different boards making up the local station electronics.
Figure shows the general geometry of the Front-end board. Fermilab is asked to produce the Front-end board, including buffering and limited digital connector, and the analog daughter board. Position of the different boards making up the local station electronics, including the analog daughter board. 1.6 mm thick. The PMT input are connected directly to this daughter board.
