unit: mm 3190-SQFP64
[LC99012A-S]
Features
• 5 V single-voltage power supply • Generates all pulses required for CCD drivers. • Generates all pulses required for video signal processing. • Built-in synchronizing signal generator that supports both EIA and CCIR. • Includes buffer circuits for directly driving the CCD horizontal transfer and reset gates. • Includes light metering and control systems for an automatic electronic iris function. • Fixed rate-of-change control allows a smooth electronic iris function to be implemented (an iris state output is provided). • Supports AGC control and a light metering mode that compensates for backlighting. • Selectable CCD storage mode (non-interlaced or interlaced) • Selectable TV scan mode (non-interlaced or interlaced) • Allows all types of external synchronization. • Built-in EXT-C.SYNC sync separator circuit • Built-in phase comparator for external synchronization • Control from external electronic shutter pulses and frame shift pulses supports one-shot imaging. • Package: 0.5 mm lead pitch flat package (SQFP-64) • Flickerless function • Sensitivity-increasing function
