CXD2470R
Timing Generator for Frame Readout CCD Image Sensor
Description
The CXD2470R is a timing generator IC which
generates the timing pulses for performing frame
readout using the ICX224,ICX284,ICX202 and ICX232
CCD image sensor.
48 pin LQFP (Plastic)
Features
• Base oscillation frequency 24.00 to 36.00MHz (max.)
• High-speed/low-speed shutter function
• Supports quadruple-speed readout drive
• Horizontal driver for CCD image sensor
• Vertical driver for CCD image sensor
Applications
Digital still cameras
Structure
