NEC Electronics Corp. has developed a PCI Express to PCI-X bridge application specific standard product (ASSP) and a PCI Express switch ASSP. Manufactured in the company's 0.15?m (UX4) process technology, the PCI Express ASSPs are targeted for use in servers, workstations and other network-related applications.

The PCI Express to PCI-X bridge ASSP will allow customers to use the PCI Express and PCI-X or PCI standard in new product designs. It also integrates a physical layer (PHY) for all PCI Express ports. The chip's upstream port features one x8 lane (also capable of operating in x4, x2 and x1 modes), and the product's downstream ports support two PCI-X bus segments and operate in both 133MHz PCI-X and 64MHz 64-bit PCI modes.

The PCI Express switch gives customers the ability to fan out more PCI Express ports in their designs. The switch ASSP includes integrated PHYs, two x8 lanes (capable of operating in x8, x4, x2 and x1 modes) for upstream ports and four x4 lanes (capable of operating in x4, x2 and x1 modes) for downstream ports.

The bridge ASSP will be priced at $38 per unit in high volume, while the switch ASSP will be available for $90.
