  1. Thoughts on C&C hardware modularity

  2. Concept • Master and Slave will be proper AMC • AMC boards will be fairly ‘smart’: • Micro-controller • Small FPGA? • So no need for custom backplane as all boards will have communication built-in • MTCA Slave is a bit of a waste of all this ... • Maybe something more modular … • Generic baseboard with plugins • Master = 1x fanout + 1x TR/beam interfaces plug-in • Slave = 2x fanout

  3. Vertical Plugins (double stack conn.) Fanout 8 Plug-in Master Plug-in To FEE FPGA TR/ Machine etc. Signals Fanout 8 Plug-in To FEE TCP/IP Local AMC Control CC Master PLL etc

  4. Layered plugins (single stack conn.) Fanout 8 Plug-in Master Plug-in To FEE FPGA To FEE TCP/IP Local AMC Control To TR or CC Master PLL etc

  5. More Thoughts • Multiple plug-ins nice as all fanouts are equal (delays etc.) • BUT a C&C baseboard with 8x fanout integrated has other advantages: • Basic unit of the C&C system is one board • Cheaper • Maybe play the same PCB but load only the parts required … • Larger FPGA (more logic/IO) on Master
