Safe Assure® (Functional Safety)
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.
TJA1101B, IEEE 100BASE-T1 Compliant Automotive Ethernet PHY Transceiver
TJA1101B is the revision of the successful TJA1101A. The high performance, single port automotive Ethernet PHY is compliant to IEEE 100BASE-T1. The device is passing all state of the art conformance test specs, including OPEN Alliance EMC Spec 2.0
- Designed according to ISO26262, it meets ASIL-A to ease the design of safe vehicles
- Being designed and fully qualified for automotive applications, the TJA1101B offers 100Mbit/s transmit and receive capability over up to at least 15m of unshielded twisted pair (UTP) cable
- The highly integrated device is robust by design, saving external filter and ESD protection components in the MDI path
- Future proof by enabling fully OPEN Alliance TC-10 compliant sleep and wakeup forwarding over the data line, it saves wire cost and weight by replacing dedicated wake-up lines
