Mezzanine connectionsASIC bonding works best if the
underneath of the pcb is flat and clean of components.
These Samtec FSI connectors only require gold plated pads on the mezzanine board.
Locators on the connectors and 15 bolts will provide alignement.

Digital channel analogue buffering
Preamp output referenced to the VREF from the ASIC and converted to differential signal centered about the ADC reference.
ASIC reference buffered once for 16 channels.
Input from ASIC

PowerPC external memory
• 16M x 64 bit DDR2 SDRAM to hold LINUX operating system, and data buffers. (400Mhz)
• Flash memory to hold FPGA fabric program and the Linux boot loader software. (Xilinx device)– Flash memory will hold a “golden” copy of each and
allow later versions to be written by the Linux system. And be selected automatically for at power-up with a “fallback” to the “golden” copy in case of failure.
