Microchip Technology PCI11101 PCIe Switch w/ USB 3.2 Host Controller

Microchip Technology PCI11101 PCIe Switch w/ USB 3.2 Host Controller combines a USB 3.2 Gen 2 host controller and programmable I/O. The Microchip Technology PCI11101 features a 4-lane (4x8GT/s) upstream port and a 2-lane (2x8GT/s) downstream port to meet the demand for higher bandwidth PCIe sub-systems in embedded applications. Certified for GEN4 compliance in PCIe Revision 4.x specifications, the device can deliver PCIe upstream using one or more lanes for flexible system architecture. The PCI11101 ensures PCIe compliance from external-facing interfaces to switch fabric and endpoint controllers.
