Introduction
The SDA 9410 is a new component of the Micronas MEGAVISION® IC set, which enables the system to reduce large area and line flickering of interlaced TV standards.
FEATUREs
• Different application modes
- SRC mode:
- High performance scan rate converter

- SSC mode:
- Split screen applications with two signal sources (e.g. double window)
- MUP mode:
- Multipicture display mode (e.g. tuner scan)
• 8 bit amplitude resolution of each input channel
- Two input channels
- Input frequency up to 27 MHz
- ITU-R 656 data format (8 wires data only and additional sync information or 8 wires including sync information)
- 4:2:2 luminance and chrominance parallel (2x8 wires)
• Two different representations of input chrominance data
- 2’s complement code
- Positive dual code
• Two flexible input sync controllers
• Vertical peaking of the input signal
• Flexible scaling of the input signal
- Flexible digital vertical compression of the input signal (1.0, ... [2 line resolution] ... , 1/32)
