DIGITAL SCAN OPERATION 100Hz Digital Scan Converter circuit 100Hz converter circuit consists of the following ICs. - SAA4977H A/D, D/A, Timing generator - SAA4991WP 100Hz converting processor - SAA4955TJ x2 1.9Mbit field memory -MC74HC4046AF PLL(Phase Locked Loop) The Y/U/V signals decoded in the HOP IC (IC101) are sent to the scan converter circuit. The Y/U/V signals are sent to SAA4977H through the AC coupling capacitors and converted to 8bit digital data with 16MHz sampling clock at the A/D converting stage in the IC respectively.
