Compact MicroTCA platform

3 March 2010 Computer/Embedded Technology

Kontron’s OM6120 is a powerful MicroTCA platform that supports up to 12 standards compliant AdvancedMC (AMC) modules. The compact system targets a wide range of quad-play telecom applications and high bandwidth datacom applications. Its streamlined design includes power management and fan control on the backplane, and pluggable power supply units instead of MicroTCA power modules. All AMC modules connect to both MCH modules in a dual-star base interface (GbE) on AMC ports 0 and 1. Fabric ports 4-7 of all AMC modules connect to MCH 1, while the AMC modules’ extended fabric ports 8-11 connect to MCH 2, enabling the OM6120 to support a wide range of configurations.

The possibility to use single and double-width form factor AMC modules provides flexibility for a wide range of applications that demand high processing power, high throughput and low latency. In combination with the layout of two rows of AMC bays, the fabric options facilitate the implementation of dual-channel processor architectures with arbitration or checkpoints between the channels. By accommodating a high number of multicore AMC modules and allowing a tight coupling of processors over high-speed communication links (over the backplane), the OM6120 is also well suited for image processing applications in single-channel or dual-channel architectures.

The port mapping and use of clocks on the backplane corresponds to SCOPE alliance (SCOPE port mapping) recommendations. This enables the synchronisation of processor AMC modules to an internal or external clock for applications such as real-time processing or complex robotic motion control. The chassis has removable mounting brackets at the sides. Since the width is less than half the size of a 19” frame, two OM6120 chassis can be mounted together in a single 19” frame, providing space for 24 modules in a 5U, 19” form factor. An extra (redundant) fan tray can be mounted on top. The system is available with pedestals for table top operation, making it suitable for lab development.

The cube design ensures efficient use of space for AMC modules while keeping the cooling simple (maximum two AMCs in-line in the air stream, or one double-width AMC). The basic OM6120 configuration contains two AC power supply units, so no extra AC-DC converters are needed. Also included in the basic configuration are two AM4901 management carrier hubs (MCH). Additional AMC processor modules such as the AM4010, AM4011 or AM4101 can be added according to customer requirements. The OM6120 AMC platform ships fully configured and tested, including an installed operating system (Windows, Linux Red Hat or WindRiver, VxWorks).
