CP320-IO1 Module CP321

A.2. Board Interfaces

PCI Expansion Connector
The PCI expansion connector CON2/3 provide all the necessary signals for data transfer as
defined by PCI Specification Rev. 2.1. This connector combination allows for board stacking
(cascading) with CON2 providing the connection to the carrier board or previous CP320-IO1
and CON3 providing connection to the next CP320-IO1 carrier. The pinouts of CON2 and
CON3 are the same.
PMC Interface
The PMC interface provides an easy way to extend the CP321 via the wide array of interfaces
and functions which are available on PMC modules produced by the entire range of PMC ven-
dors. PMC connectors provide a 32-bit wide PCI data path with a speed of up to 33MHz which
is routed to the onboard connectors Jn1 and Jn2. These connectors also provide the power
supply for the PMC module. The interface has been designed to comply with the IEEE 1386.1
specification which defines a PCI electrical interface for the CMC (Common Mezzanine Card)
form factor.
