Technical content

The AN5385K is an IC which conducts contour correction for luminance signal and color differ- ence signal. It corresponds to all broadcasting sys- tems of PAL, NTSC and SECAM. Fewer external parts enables the TV sets to be less cost and high picture quality. n Features

  • Black side contour emphasis and white side shoot elimination circuit are built in (for anti-blooming)
  • Transient correction of color difference signal (color missing improvement)
  • Red gamma correction circuit built in
  • Wider band of signal processing (Y: 7 MHz/-3 dB, Color difference: 3 MHz/-3 dB)
  • Delay time is identical for both Y and color difference.
  • Delay amount switch is built in
  • Delay line and coupling condenser built in n Applications
