The top-level design implementation for Everest DEV Board PROTO is shown in Figure 4.
Figure 4: Design Implementation
– Top Level Everest DEV Board PROTO
The top-level design implementation for Everest DEV Board Rev. A and B has an extra
CoreGPIO called
SFP_CTRL
that receives the signal
SFP_MOD
,
SFP_TX_FAULT
and
SFP_RX_LOS,
including interrupt generation for those signal, and drives the signals
SFP_TX_DIS
,
SFP_RS0
and
SFP_RS1
.
