SYSTEM INFORMATION

The WM8170 is a complete signal processing and data acquisition system which is designed to

interface directly to the analogue output of area array CCDs. The device digitises the video signals

from the CCD for subsequent digital processing of the data. The WM8170 can be used in a wide

range of CCD-based video applications such as digital still cameras, as shown in Figure 7.
