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.
