Product Description

The PI7C9X2G612GP is a 12-lane PCI Express 2.0 Switch with 6 PCI Express ports specifically designed to meet high performance and the latest Green low-power, lead (Pb)-free system requirements, such as embedded, storage, network and other platforms. The name of the family, GreenPacket, refers to Diodes' proprietary power saving technology. The PI7C9X2G612GP provides one upstream port supporting x4, and one x4 plus four x1 downstream ports operation. The flexible upstream port provides users the flexibility to expand or fan-out from a wide range of x86, ARM, MIPS, PowerPC SoC/Chipset, and it is a suitable solution for embedded, storage, wired/ wireless networking, HBA, surveillance, combo card and other applications.
