SAA4990H - Progressive scan-Zoom and Noise reduction IC

Description

The SAA5191 is a bipolar integrated circuit that extracts teletext data from the video signal (CVBS), regenerates the teletext clock (TTC) and synchronizes the text display to the television signals (VCS).

Features

  • Adaptive data slicer.
  • Crystal-controlled data clock regeneration with a bit rate of 6.9375 MHz.
  • Adaptive sync separator, horizontal phase detector and 13.5 MHz VCO to provide display phase locked loop (PLL).
  • TV synchronization at teletext mode.
