【 摘 要 】

This document describes two VME modules developed for MINERvA experiment at Fermilab. The Chain ReadOut Controller (CROC) module has four serial data channels and can interface with up to 48 front-ends using standard CAT5e networking cable. The data transmission rate of each channel is 160 Mbit/s. The maximum data transmission rate via VME bus is {approx}18 MB/s. The Chain Readout Interface Module (CRIM) is designed to provide various interface functions for the CROC module. It is compatible with MINOS MTM timing module and can be used to distribute timing signals to four CROC modules. The CRIM module also has a data port compatible with the CROC serial data interface. The data port can be used for diagnostic purpose and can generate triggers from front-end events. The CRIM module is a standard D08(O) interrupter module.
