VPPD-03980. 1.1. 4/16
Superior PHY and Interface Technology
• 10/100/1000BASE-T Ethernet copper transceiver
(IEEE802.3ab compliant) with Microsemi exclusive non-TDR
based VeriPHY™ cable diagnostics software enables testing
without taking down link or impacting data bandwidth while in
1000BASE-T mode
• Patented line driver with low-EMI voltage mode and integrated
line-side termination resistors
• WOL support using magic packets
• HP Auto-MDIX and manual MDI/MDIX support
• RGMII/GMII/RMII/MII MAC interface with widest voltage range
support in the industry: 1.5 V, 1.8 V, 2.5 V, and 3.3 V (LVCMOS)
• Jumbo frame support up to 16 kilobytes with programmable
synchronization FIFOs
• Additional internal FIFO located on ingress side enables
support for EtherCAT
®
applications
Synchronous Ethernet Support
• Recovered clock output with programmable clock squelch
control and FLF indication (<1 ms typical) for ITU-T
G.8261/Y.1361 compliant SyncE applications
• 1000BASE-T Ring Resiliency™ to switch between master and
slave timing without dropping link
• Clock output squelch to inhibit clocks during auto-negotiation
and no link status
1588v2 PTP System-Level Support
(VSC8541-03 only)
• When in RGMII mode, SOF signal (for both ingress and
egress) on line side along with synchronized 125 MHz clock
enables a high-accuracy time stamping capability when used in
conjunction with an appropriate 1588v2 time stamping engine
Best-in-Class Power Consumption
• EcoEthernet™ 2.0 green energy effi ciency with ActiPHY™,
PerfectReach™, and IEEE 802.3az EEE
• Clause 45 registers to support IEEE 802.3az EEE and
IEEE802.3bf
• Fully optimized power consumption for all link speeds
• 10BASE-Te mode support enables even lower power
consumption than 10BASE-T
Key Specifi cations
• Compliant with IEEE 802.3 (10BASE-T, 10BASE-Te,
100BASE-TX, 1000BASE-T)
• Supports GMII and RGMII (version 1.3), RMII (version 1.2), and
MII at 1.5 V, 1.8 V, 2.5 V, and 3.3 V LVCMOS
• RGMII version 2.0 timing compliant
• Supports clocking from 25 MHz crystal or 25/50/125 MHz
oscillator
• Microcontroller-free confi gurability through hardware strapping
• Optionally reports if a link partner is requesting inline Power
over Ethernet (PoE and PoE+)
• Optional stand-alone capability supports even the most cost-
sensitive Ethernet enabled designs
• Low alpha mold compound enables 80 SER FIT
(VSC8541XMV-03 only)
• Devices support operating temperatures of –40 °C ambient to
125 °C junction or 0 °C ambient to 125 °C junction
• Available in 8 mm x 8 mm, 68-pin single-row QFN package
