Product:
PCIe® 4-Port/4-Lane SlimLine^TM Packet Switch
Part Numbers: PI7C9X20404SL
Product Description
The PI7C9X20404SL is a 4-port/4-lane PCI Express®
SlimLine^TM Packet Switch specifically designed to meet the
latest low-power, lead (Pb)-free and green system
requirements. The PI7C9X20404SL is a cost-effective
solution that can be implemented in systems such as
motherboard, laptop, docking station, combo card, HBA, set-
top box, embedded system and other mobile or power-
sensitive high performance platforms. The name of the
family, SlimLine^TM, refers to Pericom’s proprietary power-
saving technology.
The PI7C9X20404SL provides one upstream port and three
x1 downstream ports. The PI7C9X20404SL provides users
the flexibility to expand or fan-out from a wide range of I/O
Bridges such as MCH, ICH, embedded MCU and other
Application Specific ICs.
