Supporting full hot swap and IPMI capabilities with a range of industry standard operating systems, the AM 90x/x1x is designed for use in AdvancedTCA®, MicroTCA or MicroTCA for Physics applications in the telecommunications, scientific, and physics research markets. Applications include media-servers or blade-servers.


The NAT-MCH-PHYS is the powerful management and data switching entity for all MicroTCA.4 systems.

Single slot solution providing MCH, fully user accessible Intel® CoreTM i7 CPU and storage

The new members of the NAT-MCH family of products, the NAT-MCH-PHYS and its associated rear-transition module NAT-MCH-RTM are leveraging additional flexibility and scalability to MTCA.4 systems. This unique combination releases slots normally occupied by PrAMCs, storage and graphic AMCs by utilizing the space behind the MCH slot(s) in a MicroTCA.4 chassis.

the NAT-MCH-PHYS is a double-width, full-size MCH, with a special clock module providing low jitter and skew, and a PCIe switch module, providing Gen3 (20Gbps) bandwidth at the fat pipe.

The clock for Physics sub-module delivers special clock functionality (CLK1-2) dedicated to Physics applications and a PCIe spread spectrum or fixed mean clock (CLK3) at HCSL level. The reference input for CLK 1/3 can be sourced from either CLK2 from one of the AMCs or from one of the CLK inputs at the NAT-MCH front panel. In addition to the standard front panel elements the NAT-MCH-PHYS offers an RS232 console port.

Optionally the NAT-MCH-PHYS can be equipped with one or two SATA Flash Drives (SSD), accessible through the Rear Transition Module (RTM) of the NAT-MCH-PHYS, the NAT-MCH-RTM.

– Support for 12 AMCs (13th AMC optional), 2 cooling units, 1-4 power modules
– Support for NAT-MCH-RTM
– GigaBit Ethernet switching (Fabric A)
– PCI Express (Gen3) switching (Fabrics D-G)
– Clock generation and distribution
– Management Controller (MCMC)
– Java based GUI for Linux and Windows Hosts

NAT MicroTCA Carrier Hub (NAT-MCH)


The NAT-MCH is a MicroTCA (uTCA/MTCA) Carrier Hub in the form factor of a single or double width, mid- or full-size Advanced Mezzanine Card (AMC). It provides the central management and data switching entity for all MicroTCA systems. The NAT-MCH comprises of a base module and numerous optional daughter cards which can be mounted on the base module. The NAT-MCH is MTCA.0, MTCA.1, MTCA.2, MTCA.3 and MTCA.4 compliant and delivers switching and hub functionality for the various system fabrics as defined in the AMC.x standard series or custom protocols based on Xilinx Kintex-7 FPGA.

CPU, memory and O/S
The NAT-MCH base board is equipped with a CPU of the Freescale ColdFire family of processors. The CPU operates at core frequency of 266 MHz. The NAT-MCH provides 32/64MB SDRAM and 16/32/64MB FLASH memory. The NAT-MCh operates on the field proven real-time kernel OK1.

Gigabit Ethernet Switch and 10GbE (XAUI) Support
The Gigabit Ethernet Switches incorporated in the NAT-MCH both provide a layer 2, non-blocking, low-latency Gigabit Ethernet switches, supporting VLAN as well as a port based rate control. The NAT-MCH supports Fabric A (1GbE) and Fabrics D-G (10GbE, XAUI) according to MTCA.0, MTCA.1 and MTCA.4 and PICMG SFP.1 R1.0, serving up to 13 AMCs as well as the update channel from the second MCH in redundant environments. Also supported are uplink ports at the front panel of the NAT-MCH in order to interconnect to other carriers, shelves or systems.

PCI Express Gen 3 Switch
The PCI Express Switching option allows PCIe Gen 3 connectivity for up to 12 AMCs at PCIe rates from x1 to x4. The PCIe chipsets provide a Quality of Service (QoS) module and are configurable in terms of a non-transparent port for multi-host support. The PCIe option can optionally provide a PCIe clock by a Spread Spectrum Clock (100MHz mean) or a fixed 100MHz clock. The clock can be provided compliant to HCSL or MLVDS signaling levels. The PCIe hub provides clustering support for six independent clusters with one configurable non-transparent upstream port. Each cluster offers its own transparent upstream port.

SRIO Gen 2 Switch
Alternatively the NAT-MCH can be equipped with a Serial Rapid I/O (SRIO Gen 2) daughther board to support uncontended low latency point-to-point connectivity between up to 12 AMC pipes. The SRIO hub supports x1 and x4 fat pipe transport density. A mixture of AMC modules with SRIO Gen 1 & Gen 2 is supported.
