Ordering number: EN 5472 Monolithic Linear IC LA7386 NTSC Video Signal Processing LSI for VCRs Overview Package Dimensions unit : mm 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. 3170-DIP36S [LA7386] SANYO : DIP36S 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. SANYO Electric Co.,Ltd.
