PAL CCD Delay Line

Overview

The LC89972M is a CCD delay line for PAL television

systems. It incorporates a comb filter for chrominance signal

and a 1H delay line for luminance signal.

Structure

• NMOS + CCD

Functions

• Two CCD shift registers (for chrominance and

luminance signals)

• CCD drive circuits

• CCD stage count switching circuit

• CCD signal adder

• Auto-bias circuit

• Sync tip clamping circuit (luminance signal)

• Center-bias circuit (chrominance signal)

• Sample-and-hold circuit

• PLL 3 × frequency multiplier

• 3 fsc clock output circuit

• RD voltage generator

Features

• 5 V single-voltage power supply

• Built-in PLL 3 × frequency multiplier circuit allows

3 fsc operation from an fsc (4.43 MHz) input.

• Control pin switchable to handle PAL/GBI and

4.43 MHz NTSC systems.

• Built-in chrominance signal crosstalk exclusion comb

filter features high-precision comb characteristics in an

adjustment-free circuit.

• Built-in peripheral circuits allow applications to be

constructed with a minimum number of external

components.

• Positive-phase signal input/positive-phase signal output

(luminance signal)
