NAMC-XLINK

Advanced Mezzanine Card (AMC) providing access to a passive PC
(NPCI-XLINK) backplane or a cPCI (NcPCI-XLINK) backplane

Overview

The XLINK-Family is an easy way to apply input / output (I/O) interfaces in PCI and CompactPCI (cPCI) form factors without any software modification in MicroTCA applications benefitting from its reliability and speed. The NAMC-XLINK is an Advanced Mezzanine Card (AMC) providing access to the passive PC backplane (NPCI-XLINK) and/or the cPCI system (NcPCI-XLINK) via PCI Express IO Extension not sacrificing hot swap and redundancy.The combination of different standards is ideal for projects requiring reduced engineering costs, time-to-market and gaining synergies of established systems.

XLINK-Family Overview:

Overview and Purpose

The NAMC-XLINK is a high performance single width, full-size Advanced Mezzanine Card (AMC) compatible with any MicroTCA system and connects systems based on different standards such as MicroTCA, PCI and cPCI. This MicroTCA system containing a processor card (i.e. NAMC-8569-CPU or NAMC-QorIQ-P40) and one or more XLINK cards delive the master functionality. The slave system is based on either PCI or cPCI standard and is controlled by the master system. The NAMC-XLINK connects the PCI Express (PCIe) backplane lane to a PCI Express External Cable Interface Connector on the front panel via a programmable re-driver circuitry for exchanging data streams.

Each NAMC-XLINK board in the MicroTCA rack will drive up to 4 slots in a passive PCI rack or up to 8 slots in a cPCI chassis up to 7 meters away, via cable, at speeds up to 2.5 Gb/s.


Functional Blocks


Re-Driver Circuitry

The NAMC-XLINK includes a re-driver circuitry to guarantee PCIe signal quality at the receiver portion of the PCI Express External Cable Interface.

The on-board Pericom PI2EQX4402D re-driver device allows users to adapt transmission characteristics to different cable lengths. Port A of the PI2EQX4402D directs the PCIe line of the AMC backplane to the PCI Express Cable Interface Connector; port C connects the PCIe line of the PCI Express Cable Interface Connector with the AMC backplane.


IPMB Interface

The NAMC-XLINK implements an IPMB interface consisting of an AVR ATmega645 microcontroller and a temperature sensor. The IPMB controller also manages the hot swap functionality and the geographical address as requested by the AMC.0 specification.


XLINK-Family

The NAMC-XLINK is a member of the XLINK-Family which enables the connection of different system platforms via a PCI Express External Cable Interface to a MicroTCA system.
