DIODES PI7C9X2G312GPBNJEX

The PI7C9X2G312GP is a 12-lane PCI Express Gen 2 Switch with 3 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, GreenPacketTM, refers to Pericom proprietary power saving technology. The PI7C9X2G312GP provides one upstream port supporting x4, and two downstream ports that support x4 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, HBA, Combo card, Surveillance, wired/ wireless Networking, and other applications.
