MODULE
Data processing unit for NMOS linear image sensor
C8799
Data processing unit with USB interface
C8799 is a data processing unit that converts video signals from an NMOS image sensor driver circuit into digital signals and transfers them to a PC.
The USB interface allows easy connection to a PC for high-speed data communications at 12 Mbps.
