General description
The SDA 9400 is a new component of the Micronas MEGAVISION® IC set in a 0.35 µm embedded DRAM technology (frame memory embedded). The SDA 9400 is pin compatible to the SDA 9401 (field memory embedded). The SDA 9400 comprises all main functionalities of a digital featurebox in one monolithic IC.

FEATUREs
• Two input data formats
- 4:2:2 luminance and chrominance parallel (2 x 8 wires)
- ITU-R 656 data format (8 wires)
• Two different representations of input chrominance data
- 2‘s complement code
- Positive dual code
• Flexible input sync controller
• Flexible compression of the input signal
- Digital vertical compression of the input signal (1.0, 1.25, 1.5, 1.75, 2.0, 3.0, 4.0)
- Digital horizontal compression of the input signal (1.0, 2.0, 4.0)
• Noise reduction
- Motion adaptive spatial and temporal noise reduction (3D-NR)
- Temporal noise reduction for luminance frame based or field based
- Temporal noise reduction for chrominance field based
- Separate motion detectors for luminance and chrominance
- Flexible programming of the temporal noise reduction parameters
- Automatic measurement of the noise level (5 bit value, readable by I²C bus)
• 3-D motion detection
- High performance motion detector for scan rate conversion
- Global motion detection flag (readable by I²C bus)
- Movie mode and phase detector (readable by I²C bus)
