PI7C9X20303UL Datasheet, PDF (1/1 Pages) Pericom Semiconductor Corporation – 3-Port/3-Lane Packet Switch

Product:
PCIe® UltraLo^TM 3-Port/3-Lane Packet Switch
Part Numbers: PI7C9X20303UL
Product Description
The PI7C9X20303UL is a 3-port/3-lane PCI Express®
Packet Switch specifically designed to meet the latest ultra
low-power, lead (Pb)-free and green system requirements.
The PI7C9X20303UL is a cost-effective solution that can be
implemented in systems such as combo card, HBA, set-top
box, embedded system, motherboard, laptop, docking
station and other mobile or dimension/ power-sensitive high
performance platforms.
The PI7C9X20303UL provides one upstream port and two
x1 downstream ports. The PI7C9X20303UL provides users
the flexibility to expand or fan-out from a wide range of I/O
Bridges such as ICH, embedded MCU, wireless chipset
CPU, and other Application Specific ICs.
