The blade design provides the possibility to cover unused faceplate elements like LEDs or push
button behind a custom overlay foil.
5.15 Faceplate Serial Interfaces
The ATCA-7470 has two serial interfaces. They are fully compliant to industry standard 16550
asynchronous communication controllers. The two Serial line interfaces #1 and #2 are
integrated in the Intel DH8900CC PCH and routed to the onboard FPGA, which distributes
them to either Faceplate, RTM, or IPMC for SOL. The serial line interfaces support baud rates up
to 115200 kbps through a programmable baud rate generator.
Serial Line Interface #1 (COM #1) and #2 (COM#2) destination
The serial line interface #1/ #2 can be routed either to the zone 3 connector or the Faceplate.
Destination selection is through IPMC or SW2-1.
The serial line interface #1 provides two different routing options:
Glue Logic FPGA <=> RTM
Glue Logic FPGA <=> Face Plate
