RTM P4 and P5
Discrete I/O (DIO)
Header Pin
Assignments
The CHAMP-AV8 Discrete I/O (DIO) signals are mapped to the RTM P4 and P5 headers as
shown below in Table A.42. DIO[0:7] are routed as single ended signals, while DIO[8:15] are
routed as differential I/O.
RTM P12
Geographical
Addressing
Header Pin
Assignments
On the CHAMP-AV8, the VITA 46 Geographical Addressing pins are routed to the CF-FPGA, so
that the CHAMP-AV8 can determine which slot it is in. These pins are also mapped to the P12
header on the RTM.
