Specification for a FERA-VXI interface
CENBG
version 2.0

MM Aleonard, JP Goudour, JL Pedroza

This document presents the specification of a FERA to VXI Interface (FVI). This unit will be useful in experiments including FERA ADCs in the EUROBALL equipement because it supplies a standard data path for the ADC's data and FERA commands depending of the EUROBALL MASTER TRIGGER and of the ANCILLARY TRIGGER.This document is the result of a meeting at CENBG between MM Aleonard, JP Goudour and the author.
