SerDes Block
The P4040/P4080 processor provides three banks of SerDes with a total of 18 lanes. Bank 1
routes eight lanes to the COM Express connector as SerDes[0:7]. Bank 2 routes four lanes to the
COM Express connector as SerDes[16:19]. Bank 3 also routes four lanes to the COM Express
connector but is unused for this module. Bank 1 provides two additional SerDes lanes on-board
for CPU debugging through the Aurora interface. See note in the
