Analog Devices Announces High Speed I2C to CAN-Physical Transceiver

Analog Devices LT3960

Analog Devices has introduced the robust high speed transceiver LT®3960 that extends a single-master I2C bus through harsh or noisy environments at up to 400 kbps 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 3.3 V LDO powers both the I2C and I2CAN buses from a single input supply from 4 V to 60 V. Alternatively, the LT3960 can be powered directly from a 3.3 V or 5 V supply.

The LT3960 is available in a 10-lead MSOP package.
