Diodes Incorporated Automotive PCIe Packet Switches: PI7C9X3G606GPQ/PI7C9X3G808GPQ/PI7C9X3G816GPQ
Third generation switches designed for high performance
The Diodes Incorporated PI7C9X3G606GPQ/PI7C9X3G808GPQ/PI7C9X3G816GPQ Automotive PCIe® 3.0 Packet Switch family is a series of 6-32 lanes PCI Express third generation switches with 6 to 16 PCI Express ports specifically designed to meet high performance, RAS (Reliability, Availability and Serviceability) and the latest power management system requirements of Zonal Central Controller, ADAS and telematics etc.
The Automotive PCIe3 Packet Switch family by Diodes Incorporated provides elastic bifurcation for upstream and downstream ports. The superior signal integrity performance enables support for long PCIe trace length with loss more than 30 dB. The Automotive PCIe 3.0 Packet Switch family are able to connect up to 15 endpoints, such as PCIe- SSD drives, and support multi-host applications and up to 8 DMA physical channels and 3 configurable Cross Domain End-Point (CDEP) ports for high performance fabric and failover applications.
