Overview
The LC89977M is CCD delay line for PAL television system that includes a chrominance signal crosstalk exclusion filter and a luminance signal 1-H delay line on chip.

FEATUREs
• 5-V single-voltage power supply
• Built-in 3 × PLL frequency multiplier circuit allows 3fsc operation from an fsc (4.43 MHz) input.
• Can be switched between the PAL/GBI, and 4.43NTSC formats by setting control pin values.
• Includes a built-in crosstalk exclusion comb filter for the chrominance signal that provides high-precision comb characteristics in an adjustment-free circuit.
• Peripheral circuits provided on chip for operation with a minimum of external components.
• Positive-phase signal input, positive-phase signal output (luminance signal)

Functions
• CCD shift registers (for chrominance and luminance signals)
• Timig generator and clock driver for CCD
• Delay time selective circuit
• CCD signal adder
• Auto-bias circuit
• Sync tip clamp circuit (luminance signal)
• Center bias circuit (chrominance signal)
• Sample-and-hold circuit
• 3 × PLL frequency multiplier circuit
• 3fsc clock output circuit
• High voltage generator for CCD Reset Drain (RD)
