MCP2561FD-H/MF

The MCP2561/2FD is a high-speed CAN device, fault-tolerant device that serves as the interface between a CAN protocol controller and the physical bus. The MCP2561/2FD device provides differential transmit and receive capability for the CAN protocol controller, and is fully compatible with the ISO-11898-2 and ISO-11898-5 standards. The Loop Delay Symmetry is guaranteed to support data rates that are up to 5 Mbps for CAN FD (Flexible Data rate). The maximum propagation delay was improved to support longer bus length. Typically, each node in a CAN system must have a device to convert the digital signals generated by a CAN controller to signals suitable for transmission over the bus cabling (differential output). It also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources.

Key features

• Optimized for CAN FD (Flexible Data rate) at 2, 5 and 8 Mbps Operation - Maximum Propagation Delay: 120 ns - Loop Delay Symmetry: -10%/+10% (2 Mbps)
• Implements ISO-11898-2 and ISO-11898-5 Standard Physical Layer Requirements
