- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information contact support or your sales representative.
TJA1120, NXP’s 1000BASE-T1 PHY, scales automotive ethernet speed grade up to the 1 Gbps. The device comes in compact package HVQFN36 (6 x 6 mm) for space constraint use cases. The PHY is drop in compatible with TJA1103 to equip assembly options of platform designs with the optimized PHY product for 100 Mbps or 1 Gbps data rate. TJA1120 supports shielded (STP) and unshielded twisted pair (UTP) cable applications. The PHY is developed according to ISO26262 and achieves ASIL B. It integrates OPEN Alliance TC-10 compliant wake-up forwarding over the ethernet data line.
