Product:
PCIe2 3-Port/12-Lane Packet Switch, GreenPacketTM Family
Part Numbers: PI7C9X2G312GP
150ns typical latency for packet running through switch
without blocking
Link Power Management
Product Description
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
o
Supports L0, L0s, L1, L2, L2/L3Ready and L3 link power
states
o
o
Active state power management for L0s and L1 states
Supports PCI-PM and ASPM of L1.1 PM Sub-state
and other platforms. The name of the family, GreenPacketTM
refers to Pericom proprietary power saving technology.
,
Supports Device Specific PME Turn-Off Message for each
downstream port
Support Access Control Service (ACS) for peer-to-peer
traffic
Support Address Translation (AT) packet for SR-IOV
application
Support OBFF and LTR
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.
