Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview

The TJA1101B is an improved version of the successful TJA1101A. High-performance, single-port Automotive Ethernet PHY compliant with IEEE 100BASE-T1. The device complies with all the latest conformance test specifications, including the OPEN Alliance EMC Specification 2.0.

• Designed according to ISO26262 standard and ASIL-A standard, making the design of safe vehicles easier

• The TJA1101B is designed for automotive applications and complies with the applicable standards, providing 100Mbit/s transmission and reception over an unshielded twisted pair (UTP) cable up to 15 meters long.

• Highly integrated device design is reliable, and no external filters and ESD protection components are required in the MDI path

• Save line cost and weight by enabling fully OPEN Alliance TC-10 compliant sleep and wake forwarding on data lines and by replacing dedicated wake lines,
