Product: SlimLine
™
PCI Express
®
to PCI Reversible Bridge
Part Numbers: PI7C9X111SL
Product Description
The PI7C9X111SL is the latest addition to Pericom’s PCI
Express
®
Bridge SlimLine™ family of solutions. With the
PI7C9X111SL, users can expect a x1 PCI Express to
32bit/66MHz PCI Reversible bridge with high performance,
very low power consumption, and a small footprint.
PI7C9X111SL offers the most effective forward & reverse
bridging solution to platforms with high bandwidth
requirement. The typical usage for this device is high
volume applications requiring a “bridge” from legacy PCI
products to new PCI Express based systems, or applications
requiring a “bridge” from new PCI Express based devices to
legacy PCI systems. The PI7C9X111SL is a versatile device
that can be used in applications including desktops, graphics
cards, combo cards, PC peripherals, MFP Printer and video
surveillance systems.
