NTSC Video Signal Processing LSI for VCRs

Overview

The LA7386 combines luminance signal processing functions

and color signal processing functions for NTSC VCRs on a

single chip. Developed as a new-generation LSI for use in

VCRs which offer increasingly higher image quality, the

LA7383 offers all of the functions needed in order to realize

improved picture quality in a dramatically compact 36-pin

package, making this device suitable for a wide range of

VCRs, from popularly priced models to high-end models.

Features

. Includes all functions required for video signal processing in an NTSC VCR.

. Supports full HQ functions.

YNR on chip (standard).

CNR on chip (external components can be removed for passthrough operation).

Detail enhancer on chip.

. Higher white clipping level (190%).

In addition to the above, also provides the following functions for excellent image quality:

Edge compensation.

Double high-pass noise canceller → permits wide-band noise reduction.

. Linear phase-type image quality adjustment → ideal image quality adjustment method, with no waveform distortion.

By adopting the 1CCD method, one comb filter (glass) has become unnecessary.

. Has a single 1H-delay CCD and a comb Y/C separation/YNR chroma crosstalk canceller function on chip.

Automatic adjustment filter on chip.

Y: LPF

C: 3.58 MHz BPF, 4.21 MHz BPF, LPF (REC)

. No adjustment required for white and dark clipping levels.

. Extremely few peripheral components (about 60 components, excluding peripheral components for the CCD).

. fsc output can be used as clock for OSD IC.

. Crystal oscillator for the on-screen display circuit is not required.

DCC circuit on chip.

. Suppresses flicker at top of screen and reduces AM noise.

High-speed AFC circuit.

Prevents color alteration and loss at top of screen when dubbing.

. Head switching noise reduction circuit on chip.

. Smallest package in the industry.

. Few components needed.
