Counting itself amongst the first, Trenton Technology has taken the wraps off a new family of host and backplane boards that support the new SHB Express (PICMG 1.3) standard defining a high-speed PCI Express interface between the system host board (SHB) and a passive backplane.
The SHB Express replaces the parallel PCI-X/PCI/ISA bus interface structure of PICMG 1.0 and 1.2 systems with PCI Express serial links to the backplane.
Representing the first in a series of products from the company supporting the new spec, the new boards include the NLT dual processor system host board, the NLI single processor system host board and the BPX3/8 SHB Express backplane.
The NLT features the Intel Xeon processor with an 800MHz system bus, including its Extended Memory Technology (EM64T) for use in both 32-bit and 64-bit applications. The NLT uses the Intel E7520 chipset to provide a dual channel DDR2-400 memory capable of supporting 8GB of memory with a maximum memory bandwidth of 6.4GB/s.
Edge connectors on the NLT provide two x8 PCI Express links, one x4 PCI Express link and five PCI Express reference clocks on edge connectors A and B. The PCI Express links provided by the NLT are capable of supporting communication to x1, x4, x8 and x16 PCI Express boards as well as PCI/PCI-X option cards via a PCI Express-to-PCI/PCI-X bridge chip on an SHB Express-compatible backplane.
Other NLT board features include dual SATA/150 interfaces, quad USB 2.0 connections, dual 10/100/1000Base-T Ethernet ports, on-board video and an optional I/O expansion board for legacy I/O support.
The NLI offers all of the features of the NLT in a single-processor form factor but is designed for applications that only need a single processor and a lower cost SHB solution.
Trenton has also designed the BPX3/8 backplane to support all full-length SHB Express-compatible system host boards. The backplane features one x16 and one x8 PCI Express slot.
A PCI Express-to-PCI/PCI-X bridge chip supports four 64-bit/66MHz PCI-X or PCI option card slots and a PCI-to-PCI bridge provides support for four additional 64-bit/33MHz PCI cards.
The backplane also features one Ethernet port, four USB 2.0 and two SATA/150 interfaces for use with SHBs that provide the optional I/O routing to edge connector C offered in the SHB Express specification.
The BPX3/8 supports the Trenton 14-slot backplane and the SHB Express (PICMG 1.3) 13-slot backplane mounting hole patterns. Input power options for the backplane include ATX, EPS and screw terminals for extended-current applications.
Available now, the NLT dual processor SHB is priced at $2,675; the NLI single processor SHB is $2,275; and the SHB Express Backplane is $832.
