System Architecture

• Clock and Trigger Generation and Distribution stay the same (RJ45-LVDS).

• Double Width ACM can service 8 ACCs.

• System can be extended in multiples of 8, in a pyramid scheme.

ACC- System Readout: Crate with 1 ACM and 8 ACCs

ACC - situation and plans

Proposed Readout Solution: •Replace the Font Panel QSFP with two SFPs; VME is left as originally presented (32-BIT, no CBLT, no interrupts, etc.)

•Data collected into Crate Master(ACM) via daisy chained SFPs•Max Rate inside chain: 6Gbps•Data Processing/Reduction possible inside ACM•Final Data readout only from ACM (SFP, CAT5, USB or VME)

Note:•The same readout method (daisy chaining of SFPs) can be used for the KOTO-style 500MHz ADCs, with data collected into the KOTO MT Module.
