Overview

The LC89975M is a lower-cost PAL-Format CCD delay line based on the LC89970M, with the sizes of chip and package miniaturized and the external parts count reduced.

Features

? 5 V single-voltage power supply

? On-chip 3× PLL circuit for 3·fsc operation from an fsc (4.43 MHz) input

? Supports PAL/GBI and 4.43 NTSC systems, selected by a control pin input

? Includes an on-chip comb filter for chrominance signal crosstalk exclusion. This adjustment-free circuit provides high-precision comb characteristics.

? Peripheral circuits included on chip to allow operation with minimal external circuits.

? Positive-phase signal input, positive phase signal output (luminance signal)

Functions

? CCD shift register (for chrominance and luminance signals)

? CCD drive circuit

? Circuit for switching the number of CCD stages

? CCD signal addition circuit

? Auto-bias circuit

? Sync tip clamping circuit (luminance signal)

? Center bias circuit (chrominance signal)

? Sample-and-hold circuit

? PLL 3× circuit

? 3·fsc clock output circuit

? RD voltage generation step-up circuit
