NXP Semiconductors TJA112x

Our expertise in In-Vehicle Networking enables products with ASIL B ISO26262 functional safety compliance, high quality and robust communication.

TJA112x 1000BASE-T1 PHY family with MACsec option is now released as part of the NXP Automotive Ethernet PHY portfolio. This latest PHY family is drop-in compatible to the earlier released TJA1103 and TJA1104 100BASE-T1 PHYs, enabling platform designs with optimized PHY product for 100 Mbps or 1 Gbps data rates. The TJA1120 is a standard 1000BASE-T1 PHY, while the TJA1121 adds MACsec functionality to NXP’s 1000BASE-T1 Automotive Ethernet PHY portfolio.
