Overview
The LC89978M is a CCD delay line for multi television
system that incorporates a comb filter to remove noise
from the chrominance signal and a 1-H delay line for the
luminance signal.
Features
5-V single-voltage power supply
Built-in 4
× PLL frequency multiplier circuit allows 4fsc
operation from an fsc (3.58 MHz) input.
Can be switched between the NTSC/M, PAL/GBI, and
PAL/M 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)
Timing 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
4
× PLL frequency multiplier circuit
4fsc clock output circuit
High voltage generator for CCD Reset Drain (RD).
