n AEC-Q100 Qualification in Progress The LT®3960 is a robust high speed transceiver that
extends a single-master I2C bus through harsh or noisy
environments at up to 400kbps using the CAN-physical
layer. One LT3960 sits near the I2C master, creating from
SCL and SDA equivalent differential buses (I2CAN) on
two twisted pairs. At the other end of the twisted pairs, a
second LT3960 recreates the I2C bus locally for any slave
I2C devices. A built-in 3.3V LDO powers both the I2C and
I2CAN buses from a single input supply from 4V to 60V. …
