The TJA1102 customer evaluation board is a low-cost hardware development tool which supports the functional evaluation of the TJA1102 (dual port) and the TJA1102S (single port) 100BASE-T1 PHY transceiver.

The breadboard 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 are taking care of the chip configuration during startup. To put the device e.g. in repeater mode, use jumper settings to configure for internal MII loopback.
