MCHPLAN8814-V/ZMXC1
Overview
The LAN8814 is a high-performance quad-port Gigabit Ethernet PHY designed for complex networking environments requiring high port density and precise synchronization. It features a QSGMII/Q-USGMII MAC interface and integrates comprehensive IEEE 1588v2 PTP support, making it ideal for time-sensitive networking (TSN) applications. The device supports 10/100/1000BASE-T standards and includes advanced features like Synchronous Ethernet (SyncE) and Fast Link Failure indication.
Why Choose This Part
The LAN8814 offers exceptional synchronization accuracy with plus or minus 8 ns PTP precision and supports one-step and two-step clock modes. Its QSGMII interface reduces PCB trace count compared to individual RGMII interfaces, while the 128-pin TQFP package provides a compact footprint for a four-port gigabit solution. Engineers benefit from advanced power management, including EEE Low Power Idle and a shutdown current of just 135 uA.
Applications
Key Specifications
Getting Started
Development is supported by the EVB-LAN8814 evaluation board, which provides a hardware platform for verifying QSGMII connectivity and PTP performance. For software integration, Microchip provides Linux drivers and the MPLAB Harmony framework to manage PHY registers via the MDIO/MDC interface. Ensure proper thermal management for the 128-pin TQFP package, as full-load quad-port gigabit operation can draw over 870 mA on the 1.27V rail.
