Introduction

The PCI11414 is a single-chip PCIe switch with an integrated USB 3.2 Gen 2 host controller, Ethernet MAC and programmable I/O. The integrated PCIe physical interfaces provide a 4-lane (4x8GT/s) upstream port and a 1-lane (1x8GT/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 PCI11414 includes a compliant PCIe implementation from external facing physical interfaces through to switch fabric and endpoint controllers. The PCI11414 includes a USB-IF and xHCI compliant USB 3.2 Gen 2 host controller which provides one USB 3.2 Gen 2 (USB Type-C) port, and three USB 2.0 HS/FS/LS (USB Type-A) ports. USB-C support is provided, with CC1 & CC2 (Configuration Control) being managed by the PCI11414. Overcurrent Sense (OCS) and Port Control are provided for control of Vbus. The PCI11414 also includes an IEEE 802.3 compliant 2.5Gbps Ethernet MAC. The integrated RGMII and SGMII interfaces support 10/100/1000Mbps and 1/2.5Gbps operation, respectively. 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 PCI11414 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.
