PCI11010/ZVX

Overview

The Microchip PCI11010/ZVX is a single-chip PCIe switch featuring an integrated Ethernet MAC and programmable I/O. It provides a 2-lane (2x8GT/s) upstream port and a 1-lane (1x8GT/s) downstream port, supporting PCIe Gen 4 line rates up to 8GT/s. The device includes an IEEE 802.3 compliant 2.5Gbps Ethernet MAC with RGMII/SGMII interfaces. It operates in a 100-pin VQFN package within the commercial temperature range of 0°C to +70°C.

Feature Summary

• PCIe Gen 4 Switch Fabric: Supports 8GT/s line rates with a maximum payload size of 512 bytes.
• Integrated Ethernet MAC: 2.5Gbps MAC supporting RGMII, SGMII, and SGMII+ interfaces for 10/100/1000/2500Mbps operation.
• Programmable I/O: Includes UARTs (RS232/RS485), SPI, SMBus, and multifunction GPIOs accessible via the PCIe endpoint controller.
• Precision Time Protocol: Supports IEEE 1588-2008 E2E and P2P one/two-step modes with programmable time compare outputs.

Applications

• Industrial PCs requiring network interface and PCIe fanout capabilities
• Embedded systems demanding high-bandwidth PCIe subsystems
• Edge computing devices needing integrated connectivity and timing synchronization

Procurement Notes

Verify the ordering suffix 'ZVX' corresponds to the 100-pin VQFN package and commercial temperature grade (0°C to +70°C). Confirm whether the specific order requires standard tray packaging or tape-and-reel configuration by checking for the 'T' identifier in the part number. Ensure compatibility with system voltage requirements and clock configurations using the internal clock farm.

Selection Notes

Select the PCI11010/ZVX for applications requiring a compact solution combining PCIe switching with Ethernet connectivity. Choose this variant over industrial grades if the operating environment remains within 0°C to +70°C. Consider the integrated clock generation feature to reduce external component count compared to solutions requiring multiple discrete clocks.

Part Context

The PCI11010 belongs to Microchip's PCIe switch family designed for embedded applications. It integrates a PCIe switch fabric, endpoint controllers, and peripheral interfaces into a single die. The ZVX suffix specifically denotes the 100-pin VQFN package format used for surface-mount assembly.
