I am looking for a high precision ADC evaluation board (or other kind of board that has on board ADC) with sample rate higher than 2M samples per second. The sampled data can than be recorded on a media card or on board memory. The board should be able to work standalone and output its clock to control out board device so that i can synchronize the ADC sampling with other devices. It is better for the board to have some DSP ability but it is not a necessary. Does anybody have any idea? Thanks!
