Note:
• Clocks to FE do
not come from the
FPGA;
• Clocks to FE are
fixed, not from
PLL.
• Clocks to FE are
routed to equal
length (+/-2.5mm)

Architecture
ACC-3
…
• New ACM can be designed
to service up to 16 ACCs.
Same module – Different Firmware
…
• Double Width ACM:
One ACM Card can
service 8 ACCs. System
can be extended in
multiples of 8, in a
pyramid scheme.
• Single Width ACM:
One ACM Card can
service 4 ACCs. System
can be extended in
multiples of 4, in a
pyramid scheme.
