SANYO LC99012A-S Datasheet
Ordering number : EN*5281A
22896HA (OT) No. 5281-1/6
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
