VSC8512XJG-03

Overview

The VSC8512XJG-03 is a 12-port Gigabit Ethernet PHY transceiver manufactured by Microchip Technology. It integrates twelve 10/100/1000BASE-T copper ports and four high-speed SerDes interfaces for fiber connectivity. The device supports SGMII, QSGMII, and SerDes MAC interfaces to connect with host processors. Electrical specifications include a supply voltage range of 1 V to 1 V, an operating temperature range from 0°C to +125°C, and data rates up to 1 Gb/s. It is housed in a BGA-672 package.

Feature Summary

• Integrates twelve 10/100/1000BASE-T copper ports with automatic crossover and polarity detection.
• Includes four SerDes media interfaces supporting 1000BASE-X and 100BASE-FX standards.
• Supports Energy Efficient Ethernet (EEE) for reduced power consumption during low activity.
• Features integrated IEEE 802.3af PoE support and VeriPHY cable diagnostics.

Applications

• High-density enterprise network switches
• Telecommunications access equipment
• Industrial networking gateways

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm pinout and configuration variants. Ensure compatibility with the required MAC interface protocols before integration. Confirm moisture sensitivity levels and reflow soldering profiles for surface-mount assembly processes.

Selection Notes

Select this component when a high port density solution is required for both copper and fiber connections. Evaluate the thermal requirements for the BGA-672 package under maximum load conditions. Verify that the host processor supports the necessary SGMII or QSGMII interface bandwidth.
