Description

The PI7C9X2G404SLQ is an Automotive compliant PCI Express® 2.1 4-port/4-lane PCI Express Switch specifically designed to be AEC-Q100 qualified and meet the latest low-power and lead (Pb)-free requirements. The PI7C9X2G404SLQ is a high-performance, cost-effective solution that can be implemented in systems such as Automotive Safety and Security, Traffic Mapping, Infotainment and Telematics platforms.
The PI7C9X2G404SLQ provides one x1 upstream port and three x1 downstream ports. The PI7C9X2G404SLQ provides users the flexibility to expand or fan-out from a wide range of Bridges such as Automotive MCU, FPGA, video processing and other application specification ICs.
