1.2 Product Overview

The CP372 Analog Output 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 software, perform

digital to analog signal conversion, and to make the analog output signal available to the appli-

cation process. The major components involved in these processes are: the Digital to Analog

Conversion Process and Communications (DAC ProComm) controller which is realized in a

field-programmable gate array (FPGA), digital to analog converters (DACs), and the front end

(process side) signal conditioning. The DAC ProComm Controller is designed to provide effec-

tive and efficient control of the digital to analog conversion process as well as interfacing to the

CPCI System Controller.

The following table provides a quick overview of the CP372 board.
