Microchip Technology PCI11414 PCIe Switch w/ USB 3.2, MAC & I/O

Microchip Technology PCI11414 PCIe Switch w/ USB 3.2, MAC, and I/O combines a USB 3.2 Gen 2 host controller, Ethernet MAC, and programmable I/O. The Microchip Technology PCI11414 offers a 4-lane (4x8GT/s) upstream port and a 1-lane (1x8GT/s) downstream port, making it ideal for boosting PCIe bandwidth in embedded applications. The device is certified for PCIe Revision 4.x specifications with a maximum line rate of 8GT/s. Use single or multiple lanes for PCIe upstream as needed. The PCI11414 ensures PCIe compliance from external interfaces to switch fabric and endpoint controllers.
