PCI11414C Single-Chip PCIe Switches

Microchip Technology PCI11414C Single-Chip PCIe Switches integrate a USB 3.2 Gen 2 host controller, an Ethernet MAC, and programmable I/O. The Microchip PCI11414C features PCIe physical interfaces providing a 4‑lane (4×8GT/s) upstream port and a 1‑lane (1×8GT/s) downstream port, supporting maximum line rates of 8GT/s to meet growing demands for higher‑bandwidth PCIe subsystems in embedded applications. The upstream link can operate over one or multiple lanes to optimize system architecture, and the device includes a fully compliant PCIe implementation extending from the external PHY interfaces through the switch fabric and endpoint controllers. PCIe Precision Time Measurement (PTM), compliant with the PCI Express Base Specification R5.0 V1.0, enables accurate timing synchronization between components by determining the relationship between local device clocks and a shared PTM Master Time domain.
