100BASE-T1 dual/single PHY for automotive Ethernet

Rev. 1 — 1 November 2017

Product short data sheet

1. General description

The TJA1102 is a 100BASE-T1 compliant dual-port Ethernet PHY optimized for

automotive use cases such as gateways, IP camera links, driver assistance systems and

back-bone networks. The device provides 100 Mbit/s transmit and receive capability over

two unshielded twisted-pair cables, supporting a cable length of up to at least 15 m. The

TJA1102 has been designed for automotive robustness, while minimizing power

consumption and system costs. For added flexibility, a single PHY version is available

(TJA1102S) in which one of the PHYs is disabled.
