CXD2450R
Timing Generator for Progressive Scan CCD Image Sensor
Description
The CXD2450R is a timing generator IC which
generates the timing pulses for performing progressive
scan readout for digital still camera and personal
computer image input applications using the
ICX098AK CCD image sensor.
This chip has a built-in vertical driver.
