TIDA-00172, Reference Design for an Interface to a Position Encoder with EnDat 2.2

TIDA-00172, Reference Design for an Interface to a Position Encoder with EnDat 2.2. This Design implements a hardware interface solution based on the HEIDENHAIN EnDat 2.2 standard for position or rotary encoders. The building blocks include the power supply for the encoder with innovative smart e-Fuse technology and robust half-duplex RS485 transceivers, including line termination and EMC protection. An auxiliary power supply and logic level interface with adjustable I/O voltage level is provided to connect to subsequent MCUs and MPUs that would run the EnDat 2.2 Master protocol stack
