The ability for customers to quickly and effectively evaluate general-purpose data converter devices is an important topic that semiconductor manufacturers must address. These systems must be simple enough to quickly and cheaply develop, while still allowing a complete evaluation platform for the target device(s). The integration of dense digital logic into the evaluation module design in the form of CPLD or FPGA technology can provide this ability. This paper documents the design of such an evaluation module, using a CPLD to implement logic control for host-less operation of multiple ADC and DAC devices. Also included is the design of a PC-to-EVM system using Visual Basic 6.0^"^, which allows the customer to evaluate the target ADC(s) using a PC interface and GUI. Each of these techniques developed for a data converter evaluation module can be used to address these same issues for a wide variety of devices.
