NCV7356单线CANBUS收发器数据手册

The NCV7356 is a physical layer device for a single wire data link
capable of operating with various Carrier Sense Multiple Access
with Collision Resolution (CSMA/CR) protocols such as the Bosch
Controller Area Network (CAN) version 2.0. This serial data link
network is intended for use in applications where high data rate is not
required and a lower data rate can achieve cost reductions in both the
physical media components and in the microprocessor and/or
dedicated logic devices which use the network.
The network shall be able to operate in either the normal data rate
mode or a high-speed data download mode for assembly line and
service data transfer operations. The high-speed mode is only
intended to be operational when the bus is attached to an off-board
service node. This node shall provide temporary bus electrical loads
which facilitate higher speed operation. Such temporary loads should
be removed when not performing download operations.
The bit rate for normal communications is typically 33 kbit/s, for
high-speed transmissions like described above a typical bit rate of
83 kbit/s is recommended. The NCV7356 features undervoltage
lockout, timeout for faulty blocked input signals, output blanking
time in case of bus ringing and a very low sleep mode current.
