CXD1254AR/AQ
CCD Camera Synchronization and Timing Signal Generator
Description
The CXD1254AR and CXD1254AQ Ics generates
the necessary synchronization and timing signals for
camera systems employing CCD image sensors
(ICX044, ICX045, ICX046, etc.).
Features
• Supports color (NTSC) and black & white
(EIA/CCIR) systems
• On-chip electronic shutter
• On-chip horizontal (H) driver
• Timing generator for mirror images
