PCIe 3.1 Ethernet bridges enable power savings for embedded, automotive platforms


MICROCHIP TECHNOLOGY LAN7430 Ethernet bridge provides integrated power, clocks and an Ethernet physical (PHY) interface while the LAN7431 provides Reduced Gigabit Media-Independent Interface (RGMII) for alternative PHYs and switches. The LPSS L1.1 (snooze) and L1.2 (off) enables designers to reduce power consumption and improve battery life by snoozing or turning off the high-speed circuits in the PHY when not in use. When connected to an application System on Chip (SoC) or processor as host, device allows the host device to deliver audio, data or video data through the 10/100/1000 Ethernet network. Connection to the host is achieved via the PCIe 3.1 specification, providing up to 2.5 Gigatransfers per second (GT/s) in each direction simultaneously.
