Product Details

Description



Features:

·Conversion of PC/AT VGA (640 ´ 480) display data into NTSC video signal
      • 8-bit inputs for VGA R, G, and B signals
         Horizontal frequency: 31.5 kHz
         Vertical frequency: 59.94 Hz
   • Conversion of non-interlaced display to interlaced display
   • Built-in phase-locked loop for synchronizing VGA and NTSC data clocks
   • Conversion from RGB to YCrCb (4:2:2) format
   • Data output in NTSC display format (YCrCb24 or YCrCb16-bit)
·Flicker prevention
   • Choice of line filters with 3 taps for preventing flicker
·Processing with only line memory
   • No need for external VRAM
   • All processing completes within built-in line memory


Application

·Point-of-sale terminals, Factory automation terminals, word processors, and other terminals
·Choice of readout clocks for NTSC output
Choice 1: Choice of clock that has arbitrary
                frequency and synchronizes with
               VGA clock
               External voltage-controlled
               oscillator in addition to built-in
               phase-locked loop
Choice 2: Choice of clock that has arbitrary
               frequency and does not synchronize
               with VGA clock
               External oscillator
Choice 3: Clock with half frequency of the VGA-dot-clock
               Choose the clock matching the NTSC encoder.
The MN89201 offers high-quality NTSC-compatible output from a compact configuration.
