Single pair ethernet such as TE Connectivity's Mini-ETH system reduces weight and increases bandwidth in commercial aircraft systems
external component count and board space in half and consumes as little as half the power of competitive solutions. The DP83TC811S-Q1’s supports the serial gigabit media independent interface (SGMII) and improves design flexibility by enabling connections to multiple switches and interfaces. As well as requiring fewer external components, the DP83TC811S-Q1 comes in a 6-mm-by-6-mm wettable flank package, which can cut the transceiver size by half. SGMII uses only four pins instead of the 12 required for reduced gigabit media independent interface (RGMII), reducing board size and number of traces and in turn simplifying the design layout.
