The SCB is the main part of the switch.
Modified SCB for WRS-FL*
The modified SCB is larger than the original one. Together with the
space saved from the removed components/connectors, the FPGA has many
pcb space around for a larger heat sink.
The clock processing and distribution of the SCB is shown
The power generation circuit has been modified from SCB_v3.4 with more
DC/DC rails to reduce overburden power
The reset/re-configure/re-program signals are connected in the following
Few components are replaced for wider temperature range or better
The SCB connects the backplane boards through two 96pins high-speed
SAMTEC board-to-board connectors. Few pins of the connectors are
different between SCB-V3.4 and SCB-FL as listed below
