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
