    5-3-8 Adaptive Comb Filter (VCT3834A only) The adaptive comb filter is used for high-quality luminance/chrominance separation for PAL or NTSC signals. The comb filter improves the luminance resolution (bandwidth) and reduces interferences like cross-luminance and cross-color artefacts. The adaptive algorithm can eliminate most of the mentioned errors without introducing new artefacts or noise.
  • Page 45 5-3-11 Video Sync Processing To extract the sync information from the video signal, a linear phase low-pass filter eliminates all noise and video contents above 1 MHz. The sync is separated by a slicer; the sync phase is measured. A variable window can be selected to improve the noise immunity of the slicer.

    5-7-2 Mode selection The TDA894xJ has several functional modes, which can be selected by applying the proper DC voltage to pin MODE. Mute : In this mode the amplifier is DC biased but not operational (no audio output). This allows the input coupling capacitors to be charged to avoid pop-noise.

  • Page 56 When the power switch is pushed on, V increases slowly. During this time, C806 is charged through R802. As soon as V reaches 16V, the STR-F6654 control circuit starts operating. Then, V is obtained by smoothing the winding voltage which appears between pin6 and pin7 of the SMPS transformer. As this winding voltage does not increase to the set voltage immediately after the control circuit starts operating, V starts dropping.
