2 Functional Description
2.1 Board Inter faces
2.1.1 Front Panel LED
The CPS3105 provides one Power Status LED on the front panel.
2.1.2 XMC Interface
The CPS3105 uses one x8 PCI Express 2.1 interface operating at 5.0 GT/s and compliant with the ANSI/
VITA 42.0 and ANSI/VITA 42.3 specifications.
XMC modules are based on 3.3 V power along with variable power (VPWR) defined as either 5 V or 12 V
in the ANSI/VITA 42.0-200x XMC Switched Mezzanine Card Auxiliary Standard specification. On the
CPS3105, the VPWR is configured to 12 V.
Note:
XMC integrators should carefully review the power ratings, cooling capacity and airflow re-
quirements in the application prior to installation of an XMC module on the CPS3105.
2.1.3 CompactPCI Serial Interface
The CPS3105 provides a standard CompactPCI Serial interface compliant with the PICMG® CPCI-S.0 R 1.0
CompactPCI® Serial Specification. The interface is comprised of one CompactPCI Serial connector, P1.
The pin assignment of the P1 connector is defined in the PICMG® CPCI-S.0 R 1.0 CompactPCI® Serial
Specification.
