TJA1121 MACsec Ethernet PHY Transceiver
NXP Semiconductors TJA1121 MACsec 1000BASE-T1 Ethernet PHY Transceiver provides an efficient HW-based solution for MACsec at a 1Gbps line rate and addresses the security concerns for future networks. 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 a compact package HVQFN36 (6mm x 6mm) for space-constrained use cases.
