Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The PCI11101-I/MXX is a PCIe switch with integrated USB 3.2 Generation 2 host controller and programmable I/O.

Description:

The Microchip PCI11101 PCIe switch (with USB 3.2 host controller) combines a USB 3.2 Gen 2 host controller with programmable I/O. The device has a 4-channel (4x8GT/s) uplink port and a 2-channel (2x8GT/s) downlink port to meet the needs of higher bandwidth PCIe subsystems for embedded applications. The device is certified for GEN4 compliance in the PCIe version 4.x specification and can use one or more channels for PCIe uplink, enabling a flexible system architecture. The PCI11101 ensures PCIe compliance from external interfaces to switching structures and endpoint controllers.
