PI7C9X2G304ELQ数据手册集成电路（IC）的专用规格书PDF

描述 Description

The PI7C9X2G304ELQ is an Automotive compliant PCI Express® 2.1 3-port/4-lane PCI Express Switch specifically designed to be be AEC-Q100 qualified and meet the latest low-power and lead (Pb)-free requirements. The PI7C9X2G304ELQ 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 PI7C9X2G304ELQ provides one x1 or x2 upstream port and two x1 downstream ports. The PI7C9X2G304ELQ 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.
