LA71525M

Ordering number : EN5843 LA71525M Monolithic Linear IC LA71525M Video/audio signal processor for VHS VCRs (single chip for Y/C/A) Overview The LA71525M is a video/audio signal processor IC for VHS VCRs. It handles recording and playback of PAL/GBI, MESECAM, and 4.43 NTSC signals. NTSC software tapes can be converted to PAL for monitoring, and the IC realizes high picture and sound quality. The IC requires no adjustments and minimizes the peripheral component count, making it possible to implement efficient signal handling at low cost.
