Microsemi – Ethernet PHY offers energy-efficiency features

The VSC8541 from Microsemi is a low-power, compact copper physical layer transceiver (PHY) intended for use in space- constrained 10/100/1000BASE-T Ethernet applications.

Housed in an 8mm x 8mm package, it features integrated line-side termination to conserve board space, lower EMI and improve system performance. In addition, integrated RGMII version 2.0 standard timing- compliant compensation eliminates the need for on-board delay lines.

The device supports the industry’s widest range of LVCMOS levels for a parallel MAC interface including 1.5V, 1.8V, 2.5V and 3.3V. It also provides 1.2V, 1.5V, 1.8V, 2.5V and 3.3V support on the MDIO/MDC interface.

• EcoEthernetTM 2.0 with Energy Efficient Ethernet (EEE) features to reduce power based on link state and cable reach
• Implements Fast Link FailureTM 2.0 with failure indication for commutator ring applications
• Configurable drive strength on MAC interface enables better control of system-level EMI
