Apparatus and method for built-in self-test of a data communications system

   
   

The present invention comprises an apparatus and corresponding method for performing a built-in self-test (BIST) of a data communications system. The apparatus of the invention includes a transmitter, a receiver coupled to the transmitter and a test control system coupled to the transmitter and receiver for measuring a data error rate of the data communications system. The transmitter, receiver and test control system are disposed on a common substrate, such as an integrated circuit.

La actual invención abarca un aparato y un método correspondiente para realizar una autoprueba incorporada (BIST) de un sistema de comunicaciones de datos. El aparato de la invención incluye un transmisor, un receptor juntado al transmisor y un sistema de control de la prueba juntado al transmisor y al receptor para medir un índice de error de los datos del sistema de comunicaciones de datos. El sistema de control del transmisor, del receptor y de la prueba se dispone en un substrato común, tal como un circuito integrado.
