PI7C9X2G404SL

Product Description

The PI7C9X2G404SL is a PCI Express® 2.0 4-port/4-lane PCI Express SlimLine Packet Switch specifically designed to meet the latest low-power, lead (Pb)-free and green system requirements. The PI7C9X2G404SL 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, SlimLine, refers to Diodes' proprietary power-saving PowerSave technology.

The PI7C9X2G404SL provides one upstream port and three x1 downstream ports. The PI7C9X2G404SL 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.
