Overview
The EVB-LAN8870B-MC evaluation board is a 100BASE-T1/1000BASE-T1 (Single-Pair Ethernet) to 100BASE-TX/1000BASE-T (Gigabit Ethernet) media converter, for use in evaluating the LAN8870B VelocityDRIVE™ 100BASE-T1/1000BASE-T1 Ethernet transceiver.
The 100BASE-TX/1000BASE-T side of the EVB-LAN8870B-MC uses a LAN8830 transceiver and a conventional RJ-45 jack with integrated magnetics. It features auto-negotiation and auto-crossover. The 100BASE-T1/1000BASE-T1 side uses a LAN8870B transceiver, with all necessary external filtering and isolation components and an automotive single-pair Ethernet connector. The LAN8870B is configured in RGMII mode, and connects to the RGMII interface of the LAN8830.
Software is provided to allow users to access the LAN8870B registers from a PC via the EVB-LAN8870B-MC’s USB port and an on-board PIC microcontroller. The board can be powered from either the EVB-LAN8870B-MC’s USB port, external 5V or a 5V power supply.
