Introduction

The PCI11101 is a single-chip PCIe switch with an integrated USB 3.2 Gen 2 host controller and programmable I/O. The integrated PCIe physical interfaces provide a 4-lane (4x8GT/s) upstream port and a 2-lane (2x8GT/s) downstream port. The device is targeted to address customer requests for higher bandwidth PCIe sub-systems within embedded applications. The maximum line rate is 8GT/s and it is certified against the GEN4 compliance program as defined in the PCIe Revision 4.x specifications. PCIe upstream can be delivered across a single or multiple lanes to accommodate best system architecture. The PCI11101 includes a compliant PCIe implementation from external facing physical interfaces through to switch fabric and endpoint controllers. The PCI11101 includes a USB-IF and xHCI compliant USB 3.2 Gen 2 host controller with one USB 3.2 Gen 2 port. USB 3.2 Gen 2 10Gbps support is provided for USB Type-A, M.2 breakout, or embedded connections. Overcurrent Sense (OCS) and Port Control are provided for control of Vbus. A programmable pin multiplexer is used to map I/O functions to package pins. This enables designers to work with either a default configuration or modify signals to best fit their application. Example signals include those associated with USB operation, through to GPIO or SMBus, which are accessed via a dedicated PCIe Endpoint Controller. Though many clocks are required for PCI11101 operation, these are generated within an integrated clock farm. Only a single-ended 25MHz clock or crystal is required externally together with a PCIe reference clock. The PCI11101 is available in a 132-pin DRQFN package in commercial (3°C to +70°C) or industrial (-40°C to +85°C) temperature ranges.
