CONNECTIVITY SOLUTIONS
PCIe2 3-Port/8-Lane Packet Switch, GreenPacket^TM Family
The PI7C9X2G308GP is an 8-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 require-
ments, such as Embedded, Storage, Network and other platforms.
The name of the family, GreenPacket^TM, refers to Pericom proprietary
power saving technology.
The PI7C9X2G308GP provides one upstream port supporting x4,
and two downstream ports that support x2 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.
