VSC8541
Single Port Gigabit Ethernet Copper PHY with GMII/RGMII/MII/RMII Interfaces
Low-power, small form-factor Cu PHY with IEEE 802.3az Energy
Efficient Ethernet (EEE), Wake-on-LAN (WoL), Synchronous Ethernet
(SyncE), Start of Frame (SOF), and Fast Link Failure 2.0 (FLF2)
indication, with widest I/O LVCMOS support.
The VSC8541 device, offered in a small 8 mm x 8 mm single-row QFN
package, 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 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: 1.5 V, 1.8 V, 2.5 V, and 3.3 V, as well as
1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V support on the MDIO/MDC interface.
It includes Microsemi’s EcoEthernet™ 2.0 technology with Energy
Efficient Ethernet and power saving features to reduce power based
on link state and cable reach. It optimizes power consumption at all
link operating speeds, and features Wake-on-LAN power management
using magic packets.
The device has a 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.
Microsemi's patented Ring Resiliency™ allows a PHY port to switch
between master and slave timing references with no link drop while in
1000BASE-T mode.
VSC8541 also includes Fast Link Failure (FLF) indication for high-
availability networks. FLF indication identifies the onset of a link failure
in less than 1 ms typical, which goes beyond the IEEE 802.3 standard
requirement of 750 ms ±10 ms (link master). In addition, the device
adds a programmable threshold for applications where indication of
even a potential link drop must be known at the microsecond level
(<10 μs).
