SJA1124 - NXP

SJA1124 Quad LIN master transceiver

The SJA1124 is a quad Local Interconnect Network (LIN) commander channel device. Each of the four channels contains a LIN commander controller and LIN transceiver with commander termination. LIN commander frames are transferred to the physical LIN bus via the LIN physical layer. The SJA1124 is primarily intended for in-vehicle subnetworks using baud rates up.
