Microchip Technology has expanded its SPE solutions with its family of LAN887x Ethernet PHY transceivers, which support 100Mbps to 1000Mbps using 1000BASE-T1 network speeds and cable lengths up to 40m for extended reach.
For interoperability across industries, the company's LAN887x PHYs are designed to be fully compliant with IEEE 802.3bp for the 1000BASE-T1 specification and IEEE 802bw-2015 for the 100BASE-T1 specification. The company has collaborated with the University of New Hampshire InterOperability Laboratory (UNH-IOL) to develop a test platform for 1000BASE-T1 conformance. For many automotive and industrial applications that work in harsh environments and must withstand extreme temperatures, these devices are also designed to be ISO 26262 functional safety ready with ASIL B classification.
These devices supply advanced diagnostics, including cable fault detection, signal quality indicator, link down and errors, built-in self-test, and temperature and voltage monitoring for increased reliability. To supply flexibility with varying connectivity needs across end applications, these PHYs support Type A operation with cable lengths up to 15m and Type B operation to support extended cable lengths up to 40m. Both operation types include four inline connectors.
The PHY is a low-power solution with EtherGREEN technology for increased energy efficiency. The OPEN Alliance TC10 Sleep and Wakeup feature supplies further power savings with a maximum of 16µA standby power consumption, which extends operating time in battery applications. An optional integrated linear regulator can optimise BOM costs by decreasing the number of components in the design.
"Our comprehensive solutions, which include PHY transceivers, bridge devices, switches and development boards, make it easier for designers to implement Single Pair Ethernet technology into their designs," said Charles Forni, vice president of Microchip's USB and networking business unit. "The low-power sleep, extended cable reach features and functional safety support make our LAN887x devices versatile and robust solutions to support our customers' expanding networking needs."
The PHYs are compatible with the company's wide portfolio of MCUs, MPUs, SoC devices, and Ethernet switches. Microchip offers a growing range of SPE solutions, including PHYs, controllers, and switches, to support data transmission speeds from 10 Mbps to 1000 Mbps.
This family of PHY transceivers is supported by comprehensive hardware evaluation platforms, such as Type A and Type B media converter kits, SFP (SGMII), USB and PCIe plug-in boards, and Linux software drivers.
