Description

The PI7C9X2G304SV 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 PI7C9X2G304SV is a high-performance, cost-effective solution that can be implemented in systems such as Embedded system, AI, IoT, IPC, Wi-Fi router, Printer, NAS, HBA, STB, PC and other power-sensitive high performance platforms.

The PI7C9X2G304SV provides one x1 (or x2) upstream port and two x1 downstream ports. The PI7C9X2G304SV provides users the flexibility to expand or fan-out from a wide range of x86, ARM and MIPS based embedded SoC/ chipset, FPGA, and other Application Specific ICs.
