Product Description

The PI7C9X118SL is the latest addition to the PCI Express® Bridge SlimLine™ family of solutions. With the PI7C9X118SL, users can expect a performance-tuned x1 PCI Express to 32bit/66MHz PCI bridge with optimal thruput performance, ultra low power, and a small footprint that are highly desirable & tailored to desktop, workstation, ultra mobile and system module applications. Ultimately, the typical usage for PI7C9X118SL is Desktop/Workstation platforms requiring the system to enable the “Legacy Subtractive Decoding Mode”. The PI7C9X118SL is a versatile PCIe-to-PCI bridging device well suited for various applications: desktop motherboards, NICs, graphics cards, combo cards, PC peripherals, and MID systems.
