A1.0 Operating in the Computer Mode
The ADC14C105 Evaluation Board is compatible with the WaveVision™ 4.0 Digital Interface Board and WaveVision™
software. You must have version 4.3 or later of the WaveVision™ software to properly test this board. You can download
the latest version from: http://www.national.com/appinfo/adc/wv4.html
When connected to the Digital Interface Board, data capture is easily controlled from a personal computer operating in
the Windows environment. The data samples that are captured can be observed on the PC video monitor in the time and
frequency domains. The FFT analysis of the captured data yields insight into system noise and distortion sources and
estimates of ADC dynamic performance such as SINAD, SNR and THD.

A2.4 Clock Circuit Solder Jumper settings
Solder jumpers are used to select the path of the clock to the ADC. While not as convenient as pin-type jumpers, these
introduce less distortion into the clock signal.
By default the following jumpers are OPEN: JP46, JP52
By default the following jumpers are shorted: JP45
