PCI11010-I/ZVX

Overview

The Microchip PCI11010-I/ZVX is a single-chip PCIe switch with an integrated Ethernet MAC and programmable I/O. It features a PCIe Gen 4 (8GT/s) switch fabric certified against GEN4 compliance, providing a 2-lane upstream port and a 1-lane downstream port. The device includes a 2.5Gbps Ethernet MAC supporting RGMII/SGMII/SGMII+ interfaces and Precision Time Protocol (IEEE 1588-2008). It operates in the industrial temperature range of -40°C to +85°C and is housed in a 100-pin VQFN package.

Feature Summary

• PCIe Gen 4 (8GT/s) switch fabric with 2-lane upstream and 1-lane downstream ports
• Integrated 2.5Gbps Ethernet MAC with IEEE 802.3 compliance and Jumbo frame support
• Precision Time Protocol (IEEE 1588-2008) for E2E and P2P synchronization
• Programmable pin multiplexer for SMBus, SPI, UART, and GPIO mapping

Applications

• Industrial PCs requiring network interface and PCIe fanout
• Embedded systems needing high-bandwidth PCIe subsystems
• Applications requiring precise time synchronization via PTP

Procurement Notes

Verify the ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'ZVX' denotes the 100-pin VQFN package. Confirm standard tray packaging unless the 'T' tape and reel option is specified. Ensure moisture sensitivity handling protocols are followed as indicated by the component's humidity sensitivity classification.

Selection Notes

Select this part when a compact solution combining PCIe switching, 2.5Gbps Ethernet connectivity, and programmable I/O is required. The industrial grade variant is suitable for environments with extended temperature ranges. Designers should account for the need for a single-ended 25MHz external clock or crystal alongside the PCIe reference clock for operation.

Part Context

The PCI11010 series addresses the demand for higher bandwidth PCIe subsystems in embedded applications. It integrates compliant PCIe physical interfaces through the switch fabric to endpoint controllers. The device supports flexible system architectures by allowing upstream links to operate across single or multiple lanes, optimizing design constraints for various platform requirements.

Replacement Considerations

The commercial grade version PCI11010/ZVX offers identical functionality but operates within a 0°C to +70°C temperature range. For tape and reel packaging options, the PCI11010T-I/ZVX variant provides the same industrial specifications with reel-based supply instead of standard trays.
