1.2 Product Overview
The CP371 Analog Input Controller is a part of a comprehensive concept to provide Compact-
PCI system integrators with a complete range of CompactPCI I/O products which include the
functions of analog input, analog output, digital input, and digital output implemented as sepa-
rate individual boards. This concept ensures a maximum degree of system design flexibility
thus allowing efficient and effective usage of available resources.
The basic functions of this board are to provide interfacing to the application (process), perform
analog to digital signal conversion, and to make the raw digitized data along with gain and offset
correction data available for further processing. The major components involved in these pro-
cesses are the front end (process side) signal conditioning, an analog to digital converter
(ADC), and the Analog to Digital Conversion Process and Communications (ADC ProComm)
controller which is realized in a field-programmable gate array (FPGA). The ADC ProComm
Controller is designed to provide effective and efficient control of the analog to digital conver-
sion process as well as interfacing to the CPCI System Controller.
The following table provides a quick overview of the CP371 board.
