Product Description
The PI7C9X2G304EL is a PCI Express® 2.0 3-port/4-lane PCI Express ExtremeLo Packet Switch specifically designed to meet the latest low-power, lead (Pb)-free and green system requirements.
The PI7C9X2G304EL is a high-performance, cost-effective solution that can be implemented in systems such as Embedded system, Wi-Fi router/ gateway, printer, storage, combo card, HBA, set-top box, motherboard, laptop, docking station, and other power-sensitive high performance platforms. The name of the family, ExtremeLo, refers to the proprietary power-saving PowerSave™ technology.
The PI7C9X2G304EL provides one x1 or x2 upstream port and two x1 downstream ports. The PI7C9X2G304EL provides users the flexibility to expand or fan-out from a wide range of I/O Bridges such as PCH, ICH, IOH, embedded MCU, FPGA, and other Application Specific ICs.
