LA7685J
PAL/NTSC Single-chip Color Television Signal Processing Circuit
Overview
LA7685J single-chip (with VIF, SIF, video, chroma, deflection circuits built NTSC television sets. Because PLL+ splitting method used circuit, LA7685J suited top-of-the-line small mid-size television sets. addition, when used combination with LA7640N SECAM chroma LA7685J used PAL/NTSC/SECAM multisystem set.
Features
[VIF Block] PLL+ splitting (for excellent image sound quality) High-gain amplifier High-speed time constant switch built [SIF Block] Simultaneous audio IN/OUT Video/audio simultaneous muting, audio only muting also possible amplifier with function Switching Block] INT/EXT switch
[Video Block] Black extension restoration Delay line built Wide band: (with delay line shorted) Built-in double differential circuits that also enable soft tone Supports input (for VCRs) transmission amount varied (externally adjustable) [Deflection Block] Adjustment-free horizontal vertical sync Excellent anti-noise characteristics adoption duplex Vertical sync sensitivity adjusted externally Constant vertical size with signal (constant 60/50 Highly stable image during copy guard tape playback (macrovision tapes, etc.) Excellent stability against skew distortion
