Pericom Semiconductor introduces PCI-X bus bridge for I/O-intensive Gigabit Ethernet, Fibre Channel, and RAID

Pericom Semiconductor Corporation has expanded its SiliconConnect PCI bridge portfolio with a powerful PCI-X to PCI-X bridge that targets bus expansion in next-generation high-bandwidth data communication and telecommunication applications.

Pericom's 2-port P17C21P100 supports the full 64-bit/133MHz specification for PCI-X, and is also backward-compatible to conventional PCI down to 32-bit/33MHz. P17C21P100 is a pin compatible superset to the Tundra TSI310 (formerly IBM21P100), with three key additional features that many customers are finding attractive: Dynamic Prefetching Control, Configurable Free Space in the Memory Data FIFO, and 5V tolerance in support of legacy products.

Typical applications for the P17C21P100 PCI-X to PCI-X bridge include Quad Gigabit Ethernet Cards, Quad Fibre Channel Cards, Dual & Quad SCSI RAID Controller Cards, High-end Video/Imaging Cards, Single Board Computers, Network Infrastructure for Mobile Wireless, Modem Card for 3G Base Station, and Industrial PCs. Pericom is also very committed to and focused on the emerging PCI-Express and Advanced Switching Interconnect standards.

Key Features:

--64-Bit/133MHz;

--Backward compatible to conventional PCI;

--Dynamic Prefetching Control (Unique algorithm for handling Memory Read transactions);

--Configurable free space in the Memory Data FIFO (Enhanced method for Memory Write transactions);

--Asynchronous mode support;

--Support for 6 Secondary Bus Masters;

--Support for up to 8 active transactions in each direction;

--3.3V signaling with 5V tolerance;

--Extended Commercial Temp Range (0[degrees]C to 85[degrees]C).
