Description
CCD linear image sensor output signal. This device
is suitable for 3 lines of full-color CCD linear image
sensor (ILX516K/ILX518K/ILX520K: 3648 pixels
3 lines/5363 pixels
This device has a built-in sample-and-hold, clamp,
multiplex, gain control amplifier circuits and can be
connected directly with external AD converters.
(Sony’s CXD2311AR, CXD1175AM or CXA1977R
are recommended as AD converters.)
Features
• Sample-and-hold circuit
• Pixel-clamp and line-clamp circuit
• Multiplex circuit
• ADC driver circuit
• Gain control amplifier circuit
• Offset control circuit
• Clock frequency: 1.5 to 6MHz (after multiplex)
Applications
Structure
