7.0 Functional Description
7.1 General
The AMIS-30663 is the interface between the CAN protocol controller and the physical bus. It is intended for use in automotive and industrial applications
requiring baud rates up to 1Mbaud. It provides differential transmit capability to the bus and differential receiver capability to the CAN protocol controller.
It is fully compatible to the "ISO 11898-2" standard.
7.2 Operating Modes
AMIS-30663 only operates in high-speed mode as illustrated in Table 3.
The transceiver is able to communicate via the bus lines. The signals are transmitted and received to the CAN controller via the pins TxD and RxD. The
slopes on the bus lines outputs are optimised to give extremely low EME.
