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)
