The TJA1100HN customer evaluation board is a low-cost hardware development tool which supports the functional evaluation of the TJA1100HN 100BASE-T1 PHY transceiver. The board provides straight access to the MDI and MII interfaces of the chip. The 40-pins standard header allows for quick connection to the host controller. Simple screw connectors adapt flexibly an (unshielded) twisted pair of wires. Jumper settings take care of the chip configuration during startup.
