CHANDLER, Ariz., Sept. 16, 2020 — Ethernet Physical Layer TransceiverThe LAN8770 Ethernet Physical Layer Transceiver from Microchip Technology Inc. is an OPEN Alliance TC10 sleep standard device.

With a single port, it is compliant with the IEEE 802.3bw-2015 specification and available in a 5 × 5-mm or 6 × 6-mm wettable-flanks quad-flat no-leads package. Its compact size is ideal for space-constrained applications such as the infotainment head unit, telematics modules, or advanced driver assistance systems. It provides 100-Mbps transmit and receive capability over a single unshielded twisted pair, exceeding automotive electromagnetic interference requirements.

The transceiver simplifies customers’ end-product ISO26262 safety certification with the support of specialized hardware safety features, failure modes, effects, and diagnostic analysis, and safety manual. The LAN8770M and LAN8770R support communication with an Ethernet MAC via standard MII/RMII and MII/RMII/RGMII interfaces, respectively. An optional 125 or 50 MHz reference clock output is also provided for RGMII and RMII applications, often enabling elimination of an external reference clock.
