Overview
   The VSC8541-01 device is designed for space-constrained 10/100/1000BASE-T applications. It features integrated, line-side termination to conserve board space, lower EMI, and improve system performance. Additionally, integrated RGMII timing compensation eliminates the need for on-board delay lines.

   Microsemi’s EcoEthernet™ v2.0 technology supports IEEE 802.3az Energy-Efficient Ethernet (EEE) and power-saving features to reduce power based on link state and cable reach. VSC8541-01 optimizes power consumption in all link operating speeds and features a Wake-on-LAN (WoL) power management mechanism for bringing the PHY out of a low-power state using designated magic packets.

   Fast link failure (FLF) indication for high availability networks identifies the onset of a link failure in less than 1 ms typical to go beyond the IEEE 802.3 standard requirement of 750 ms ±10 ms (link master). Potential link failure events can be more flexibly monitored using an enhanced FLF2 state machine, which goes beyond FLF indication by enabling signaling of the link potentially going down within 10 µS.

   The device includes recovered clock output for Synchronous Ethernet applications. Programmable clock squelch control is included to inhibit undesirable clocks from propagating and to help prevent timing loops. Ring Resiliency allows a PHY port to switch between master and slave timing references with no link drop in 1000BASE-T mode.
