TJA1121 adds MACsec to NXP’s 1000BASE-T1 Automotive Ethernet PHY portfolio. It addresses the security concerns for future networks and provides an efficient HW based solution for MACsec at 1 Gbps line rate. To enable speed grade scaling for platform designs with and without MACsec, the TJA1121 is kept drop in compatible with TJA1103, TJA1104 and TJA1120. The device comes in compact package HVQFN36 (6 x 6 mm) for space constraint use cases.
TJA1121 complies with all state-of-the-art conformance test specifications and is designed according to ISO 26262 to meet ASIL B, providing enhanced monitoring and diagnostic features. Further, it integrates OPEN Alliance TC-10 compliant wake-up forwarding over the Ethernet data line. It supports shielded (STP) and unshielded twisted pair (UTP) cable applications.
When it comes to functional safety, NXP stands for quality and reliability. Our SafeAssure program simplifies system-level safety requirements in accordance with ISO 26262.
