Overview
The LC99012A-S is a timing generator for the 1/5-inch LC9947G and LC9948G and the 1/6-inch LC9949G black-and-white CCD image sensors.

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
