TJA1101B
description
The TJA1101B is a 100BASE-T1-pliant Ethernet PHY optimized for automotive use cases such as gateways, IP camera links, radar modules, driver assistance systems and back-bone networks. The device provides 100 Mbit/s transmit and receive capability over a single unshielded twisted-pair cable, supporting a cable length of up to at least 15 m. The TJA1101B has been designed for automotive robustness and ISO 26262, ASIL-A pliance, while minimizing power consumption and system costs.
Being ASIL-A pliant, adequate safety features have been implemented to ensure that ASIL requirements are met at system level. Additional documentation, including a safety manual, is available on request.
The TJA1101B supports OPEN Alliance TC-10-pliant sleep and wake-up request forwarding, with an always-on power domain connected directly to the battery supply without the need for a dedicated voltage regulator.
