Overview
The LC89970 and LC89970M are CCD delay lines for PAL
television systems. It incorporates a comb filter for
chrominance signal and a 1 H 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
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)
