LC89971

Multi-system CCD Delay Line

SANYO -> Panasonic 

Ordering number : EN4900A

MOS IC

LC89971, 89971M

Multi-system CCD Delay Line

Overview

The LC89971 and LC89971M are CCD delay lines for multi

television systems. They incorporate 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 4 × frequency multiplier

• fsc clock output circuit

• RD voltage generator

Features

• 5 V single-voltage power supply

• Built-in PLL 4 × frequency multiplier circuit allows

4 fsc operation from an fsc (3.58 MHz) input.

• Control pin switchable to handle NTSC/M, PAL/GBI

and PAL/M 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)
