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
