LA7437 - Video Signal Processing IC

Features

  • Completely adjustment free The AGC, carrier, deviation, and PB-Y level are adjustment free. The YC record current can also be made adjustment free by using the LA7437, 7437A as the head amplifier.
  • Support for NAP and PAL color array correction Full modulation using a balanced modulator allows playback and conversion to PAL format of NTSC signals recorded on tape.
  • Crosstalk exclusion in combination with a specialpurpose CCD Crosstalk can be excluded without using a g.

Ordering number : EN5473 Monolithic Linear IC LA7437, 7437A Video Signal Processing IC for VHS VCR Systems Overview The LA7437, 7437A is a video signal processing singlechip IC that handles the PAL-G, B and I, 4.43 NTSC, and MESECAM formats. IC internal trimming is used to make the LA7437, 7437A is completely adjustment free, and in combination with a special-purpose CCD (the LC89973M) it provides a significant reduction in external components, including the glass delay line. Thus the LA7437, 7437A can significantly reduce the signal processing board manufacturing costs. Furthermore, the LA7437, 7437A supports the NAP format (NTSC to PAL conversion) that is poised to become widespread in Europe, China and other markets.
