Chapter 2 Applications and Overview
2.4 Common Options
UTCA-5503 connects to each AMC through one channel which consists of a high
speed differential transmit and receive pair (Star topology). Receive/transmit cross-
over wiring is implemented on the uTCA backplane. Systems utilizing two (redun-
dant) MCH’s may be used to implement Dual Star topologies. The Advantech MCH
supports a Gigabit Ethernet interface for the common options utilizing a 1000Bx
(SERDES) interface to the backplane. Other fabric implementations are not sup-
ported. The two MCH’s of an uTCA system have a cross connection for the base fab-
ric which may be used for cascading / linking the base fabric switches.
2.5 Fat Pipes
Fat pipes are optional and may be used for any kind of switch fabric interconnects.
Each MCH connects to the AMCs with 4 channels each in a Star topology.
Typical fabrics supported are:
! PCIe
! SRIO
! GbE
! XAUI
