PCI Express
The PCIe Gen3 bus is routed to the P15 XMC1 connector in accordance with the ANSI/VITA 42.3
standard. The interface enables you to connect XMC expansion modules with a set of links x1, x2,
x4, x8. A PCIe x4 link is routed to the P15 XMC2 connector. It can be used if the link on the XMC1
is narrowed down to x4.
PCI
The PCI bus is implemented on the Pericom PI7C9X130 reversible bridge chip connected to the
PCIe x2 bus. The following operating modes are supported: PCI 32bit/33MHz, PCI 64bit/66MHz.
The operation is supported both in the system and in the peripheral slot.
Audio
Support can be implemented via RIO (HD Audio Interface).
COM0
The debug COM port is routed to the IDC connector on the board.
LEDs
The LEDs for indication of startup diagnostics, drive activities, as well as User LEDs are routed to
the front panel. The diagnostics LED enables you to distinguish 4 board states: power OFF, power
ON, BIOS start, BIOS shutdown (operating system start). The drive activities LED informs about
the activities of the SATA interfaces. Two program-controlled LEDs are intended for user needs.
Watchdog
The module is equipped with a watchdog timer, which is built into the supervisor's microchip and
has a fixed actuation interval (1.6 s).
Power supply reset and monitoring
The CPU reset signal is generated from the following sources:
From the supervisor during power-up;
From the reset button;
From the watchdog timer;
From the Reset# signal of PCI bus (in the Slave mode).
Jumpers
The board has a switch for resetting BIOS settings to default settings.
3.2 Module Interfaces
3.2.1 PMC/XMC interface
The top side of the CPC507 board has connectors for PMC/XMC expansion modules, see
Figure 2-
2: Location of the main components of CPC507, top view
.
CPC507 supports two XMC/PMC modules:
PCI-X 64bit/66MHz bus is routed to P1-P4 PMC1 and PMC2 connectors (ANSI/VITA 39,
PCI-X for PMC and Processor PMC);
PMC I/O P4 is routed to RIO for the both mezzanines (PICMG PMC on CompactPCI R1.0
Specification).
PCIe x8 Gen3 bus is routed to the P15 XMC1 connector (ANSI/VITA 42.3, XMC: PCI Express
Protocol Layer), can be used in the x4 mode for two mezzanines.
