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)
