Pci Mezzanine Card (Pmc) Interface - Motorola MVME2300 Series Installation And Use Manual

At the physical layer, the Ethernet interface bandwidth is 10Mbit/second
for 10BaseT. For the 100BaseTX, it is 100Mbit/second. Refer to the
BBRAM/TOD Clock memory map description in the MVME2300 Series
VME Processor Module Programmer's Reference Guide for detailed
programming information.

PCI Mezzanine Card (PMC) Interface

A key feature of the MVME2300 family is the PCI bus. In addition to the
on-board local bus devices (Ethernet, etc.), the PCI bus supports an
industry-standard mezzanine interface, IEEE P1386.1 PCI Mezzanine
Card (PMC).
PMC modules offer a variety of possibilities for I/O expansion such as
FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer
Mode), graphics, Ethernet, or SCSI ports. For a complete listing of
available PMCs, go to the Mezzanines International Web site at
. The MVME2300 supports PMC front panel
and rear P2 I/O. There is also provision for stacking one or two PMC
carrier boards, or PMCspan PCI expansion modules, on the MVME2300
for additional expansion.
The MVME2300 supports two PMC slots. Two sets of four 64-pin
connectors on the base board (J11 - J14, and J21 - J24) interface with 32-
bit/64-bit IEEE P1386.1 PMC-compatible mezzanines to add any
desirable function.
Refer to
of the PMC connectors. For detailed programming information, refer to the
PCI bus descriptions in the MVME2300 Series VME Processor Module
Programmer's Reference Guide and to the user documentation for the
PMC modules you intend to use.
