Camarillo, Calif. — Vitesse Semiconductor Corp. has unveiled its latest generation of energy-efficient SimpliPHY Gigabit Ethernet (GE) devices — the VSC8501, VSC8502, and VSC8514 single, dual and quad PHYs — targeted at IoT networks transitioning to Gigabit Ethernet speeds. The new physical layer transceivers, featuring the company’s Energy Efficient Ethernet (EEE) EcoEthernet 2.0 technology, may be used in a variety of low-power, small-form factor IoT devices, such as digital signage and IP cameras.
“Ethernet is the most widely used networking interface in today’s wired and wireless networks, with virtually all data, voice and video traffic traversing multiple Ethernet links,” said Vitesse. “Emerging IoT networks are transforming everyday devices into a new category of sensor-laden intelligent end-points that can communicate and process information.”
“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, in a statement. “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.”
The GE PHYs deliver a small footprint in commercial and industrial temperature ranges, flexible configurations, and synchronous Ethernet support. Here are the details:
- Compact footprint with commercial and industrial temperature support: The VSC8502 is said to be the industry’s smallest form factor dual 10/100/1000BASE-T GE PHY with a GMII interface, while the VSC8514 is housed in 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 bill of materials (BOM) costs, and providing industrial temperature support from -40 ˚C to 125 ˚C.
- Flexible configuration: 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, said the company.
- Energy efficient: Gigabit Ethernet links typically compound energy usage by drawing power at near full levels even while standing idle, waiting for data packets, according to the company. The GE PHYs incorporate Vitesse’s EcoEthernet 2.0, offering IEEE 802.3az idle power savings up to 85 percent compared to 1000BASE-T full data rate.
- Synchronous Ethernet support: All the devices feature recovered clock output to support timing synchronization in accordance with ITU-T Recommendation G.8261/Y.1361.
- Robust features meet SONET-grade requirements: Fast link failover and ring resiliency features are said to enable OEMs to meet carrier grade resiliency and latency requirements.
