DESCRIPTION

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.

Alternatively, the LT3960 can be powered directly from a

3.3V or 5V supply.
