Small signal analog input slot card

Abstract

An interface system comprises an analog-to-digital converter and a logic circuit. The analog-to-digital converter includes an input coupled to an input terminal to receive an analog signal and includes an output to provide a digital signal in response to the analog signal. The logic circuit includes an input coupled to the output of the analog-to-digital converter and performs a signal integrity test on the digital signal. The logic circuit includes a first output to provide a first data signal to a first communication line in response to the digital signal and includes a second output to provide a second data signal to a second communication line in response to the digital signal. In one embodiment, the second communication line is a redundant line to the first communication line.
