DS6345 CAN Board

SCALEXIO I/O board for CAN and CAN FD bus systems with 8 channels and SIC support

The DS6345 CAN Board is the interface between a SCALEXIO system and CAN/CAN FD bus systems. This board is similar to the well-established DS6342 CAN Board but supports signal improvement capability (SIC) in addition. This allows higher baud rates and more stable connections.

The DS6345 provides eight channels for development and test applications, which makes it ideal for compact test systems with a limited number of available slots, such as the SCALEXIO AutoBox or the eight-slot SCALEXIO LabBox.

Network management functions such as wake-up and sleep are also included as are software-configurable, CAN feed-through, and termination circuit.
