NXP Semiconductors TJA110x PHYs for Automotive Ethernet
NXP Semiconductors TJA110x PHYs for Automotive Ethernet are 100BASE-T1 compliant dual-port PHYs to compliant single and dual-port PHYs. These PHYs provide 100Mbit/s transmit/receive capability over just two wires of the unshielded twisted-pair cable and supports a cable length of up to 15m. The TJA110x PHYs are designed for automotive robustness, minimum power consumption, and reduced system costs.
