PI7C9X2G303EL (PCIe Switch)
PI7C9X2G303EL
3-Port, 3-Lane, ExtremeLo™ PCIe2.0 Packet Switch
Product Description
The PI7C9X2G303EL is a PCI Express
®
2.1 3-port/3-lane PCI Express ExtremeLo™ Packet Switch specifically designed to meet the latest
low-power, lead (Pb)-free and green system requirements. The PI7C9X2G303EL 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 Pericom’s
proprietary power-saving PowerSave™ technology.
The PI7C9X2G303EL provides one x1 upstream port and two x1 downstream ports. The PI7C9X2G303EL 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.
