Device and method for generating a trigger signal in a position-measuring device and corresponding position-measuring device

A device for generating an asynchronous trigger signal in a position-measuring device which has a position-sensing unit, a processing unit and an interface unit, and is connectable via the interface unit and a bidirectional data channel to subsequent electronics for communication purposes, the device comprising:

• a trigger unit configured to receive an asynchronous data stream from the subsequent electronics and a synchronous data stream from a synchronization unit configured to generate the synchronous data stream by sampling the asynchronous data stream in a time pattern of a clock signal, the trigger unit comprising:
• an evaluation unit configured to detect an enable condition for outputting the asynchronous trigger signal by evaluating the synchronous data stream and to generate a gate signal, and
• a trigger signal output unit configured to receive the gate signal and generate the asynchronous trigger signal upon the gate signal being present and a signal edge of the asynchronous data stream occurring.
