CESX

PROCESSOR
Intel® Xeon™ processors at speeds of 2.8GHz to 3.6GHz*
Processor Package: FC-mPGA4 package (604-pin)
 *Higher speeds as available

CHIPSET
The CESX uses the Intel® E7520 chipset featuring an 800MHz system bus, Hyper-Threading Technology and a dual channel DDR2-400 memory interface. Three x8 PCI Express interfaces are supported by the CESX’s chipset. See the PCI Express Interfaces section for details on how the CESX implements PCI Express. The Intel® E6300ESB I/O Controller Hub supports the CESX’s dual Serial ATA/150 ports, four USB 2.0 interfaces, dual Ultra ATA/100 interfaces and the video and Ethernet controllers. The I/O Controller Hub’s LPC interface is routed to the board’s controlled impedance connector and supports an optional I/O expansion board (Core’s CE-00030) for legacy I/O and serial port communications. Communications between the Intel® E7520 Memory Controller Hub and the I/O Controller Hub occurs over a 266MB/s Hub Interface.

DUAL ETHERNET INTERFACES - 10/100/1000BASE-T
The CESX’s Gigabit Ethernet Controller (Intel® 82546EB) connects to the I/O Controller Hub via a PCI-X 64-bit/66MHz interface to provide high-speed 10/100/1000Base-T Ethernet interfaces on LAN ports 1 and 2. RJ-45 connectors, located on the I/O bracket, provide the physical interface to the Ethernet network.

DUAL SERIAL ATA/150 PORTS
The primary and secondary Serial ATA (SATA) ports on the CESX boards comply with the SATA 1.0 specification and support two independent SATA storage devices such as hard disks and CD-RW devices. SATA technology provides lower pin counts, reduced signaling voltages, simplified cabling, CRC error detection and hot-plug support. SATA produces higher performance interfacing by providing data transfer rates up to 150MB per second on each port.

CACHE MEMORY (L2 AND L1)
The Intel® Xeon™ processor’s level two (L2) cache memory is an integrated on-die Advanced Transfer Cache memory that is 8-way set associative with ECC and runs at the full processor core frequency. The L2 cache memory size is 1MB for the most common embedded processors used on the CESX. Non-embedded Intel® Xeon™ processors with a 2MB L2 cache memory are also available for use, contact Core for ordering details.

The Intel® Xeon™ processors have a 16K level one (L1) data cache.

DDR2-400 MEMORY
The four DIMM sockets on the CESX support a total memory capacity of 8GB and the DDR2 memory interface can operate as either a single-channel or dual-channel interface. The theoretical maximum memory bandwidth for single-channel operation is 3.2GB/s and 6.4GB/s for dual-channel mode. Each of the channels (A and B) terminates in two dual in-line memory module (DIMM) sockets. The System BIOS automatically detects memory type, size and speed. The memory modules used on the CESX must be PC2-3200 compliant. The CESX supports a DDR2-400 memory interface speed. Modules with a faster memory speed may be used; however, they will be automatically clocked down to the DDR2-400 memory interface speed by the System BIOS and the SHB’s memory interface components.

DDR2-400 MEMORY DIMM SLOT POPULATION
DDR2-400 memory modules are available as either single rank or dual rank DIMMs. A rank refers to the 72-bit unit of devices or DRAM chips that make up the PC2-3200 ECC registered 240-pin DDR2-400 DIMM. Single or dual rank memory modules must be placed in the CESX's DIMM sockets using prescribed population rules to ensure proper memory interface operation and performance.

ULTRA XGA VIDEO INTERFACE
The CESX is equipped with the third generation ATI® RAGE™ MOBILITY™ MI video controller. The M1 enables 2D/3D video acceleration and provides 8MB of integrated video memory. In 2D mode the video controller supports pixel resolutions up to 1600 x 1200, and in 3D mode the maximum resolution provided is 1280 x 1024. The maximum color depth supported at these extremes is 16.7 million colors. Software drivers are available for popular operating systems.

The high-performance Intel® Xeon™ processors used on the CESX may consume over 100 Watts of power. The CESX’s cooling system uses a high-reliability fan mounted to the SBC.

MECHANICAL
An active cooling system is used on the CESX to ensure reliable processor operation at elevated temperatures. Overall dimensions for the CESX, including the active cooling system, are 13.3” L (338mm) x 4.976” H (126.4mm) x 2.3” W (58.4mm).

Note: The PICMG 1.3 board height specification is approximately .176” (4.47mm) taller than the PICMG 1.0 specification. However, relative PICMG 1.3 board height off the backplane is the same due to the shorter edge connectors of a PICMG 1.3 system host board and the shorter PCI Express connectors on a PICMG 1.3 backplane.

PCI EXPRESS™ INTERFACES
Core's CESX system host board provides two x8 PCI Express links, one x4 PCI Express link and five PCI Express reference clocks routed to edge connectors A and B. These PCI Express links are used on SHB Express™ backplanes to support PCI Express option cards and bridge chips that provide PCI/PCI-X option card support. During system initialization the CESX automatically negotiates with the devices connected to the PCI Express links in order to set up communication between these devices. The net result is that the CESX system host board supports communication to x1, x4, x8, x16 PCI Express boards and PCI Express switch chips as well as PCI/PCI-X cards via PCI Express-to-PCI/PCI-X bridge technology on the backplane.
