Vitesse Unveils Energy Efficient Gigabit Ethernet PHYs

Vitesse Semiconductor introduced the latest generation of its SimpliPHY Gigabit Ethernet (GE) PHYs based on its Energy Efficient Ethernet (EEE) EcoEthernet 2.0 technology, which offer IEEE 802.3az idle power savings up to 85 percent compared to 1000BASE-T full data rate.


The new physical layer transceivers are designed for a variety of low-power, small-form factor IoT devices, such as digital signage and IP cameras.

“Vitesse is already experiencing strong demand for network infrastructure equipment designs that will support IoT traffic,” said David Grant, senior product marketing manager at Vitesse. “With the VSC8501, VSC8502 and VSC8514, we broaden our market reach into industrial IoT applications using low-power, small-form factor end-point devices connected via Gigabit Ethernet.”

Key features:

• The VSC8502 is the industry’s smallest form factor dual 10/100/1000BASE-T GE PHY with a GMII interface, while the VSC8514 employs the smallest form factor package used in the industry for a quad GE PHY. The small packaging enables a reduction in design form factor, reducing system BOM costs, and delivers  industrial temperature support from -40 ˚C to 125 ˚C;
• The VSC8501 and VSC8502 are pin-compatible, allowing system flexibility within the same footprint. They also are Vitesse’s first to feature Wake-on-LAN (WoL) support, allowing remote wakeup of target host systems from a power-savings
sleep state;
• The GE PHYs incorporate Vitesse's EcoEthernet 2.0,
• Synchronous Ethernet support: All the devices feature recovered clock output to support timing synchronization in accordance with ITU-T Recommendation G.8261/Y.1361; and
• Robust features meeting SONET-grade requirements: Fast link failover and ring resiliency features enable OEMs to design to meet carrier grade resiliency.
