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.
