SCAN CONVERTER
DESCRIPTION
The M65656FP is an integrated circuit that converts analog VGA
inputs directly into NTSC/PAL TV format outputs.
This circuit integrates a digital NTSC/PAL encoder with 8bit ADC's
and 10bit DAC's.
FEATURES
• VGA picture signal to NTSC / PAL signal conversion
• Input Format, 60Hz, 640×480 (Standard VGA format)
• High performance Non-Flicker Filter
• Built-in Line Memories
Fully integrated with no external memory requirement
• Built-in triple 8bit-A/D converters for RGB
• Built-in triple 10bit-D/A converters for TV signal outputs
• Single +3.3V Power Supply
