PI7C9X20303UL (NRND)

Not Recommended for New Design

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.
