AIDA Mini TLU
Overview
A Trigger/Timing Logic Unit designed for use with High Energy Physics beam-tests. Provides a simple and flexible interface for fast timing and triggering signals at the AIDA pixel sensor beam-telescope. Implemented as a double-width FMC with single LPC connector. Compatible with EUDET JRA1 TLU.
