LC89978M
CCD Delay Line for Multi-System
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)
