[Micronas]

General description
The SDA 9401 is a new component of the Micronas MEGAVISION® IC set in a 0.35 µm embedded DRAM technology (field memory embedded). The SDA 9401 is pin compatible to the SDA 9400 (frame memory embedded). The SDA 9401 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 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)
• TV mode detection by counting line numbers (PAL, NTSC, readable by I²C bus)
• Embedded memory
   - 3.2 Mbit embedded DRAM core for field memories
   - 128 kbit embedded DRAM core for line memories
• Flexible clock and synchronization concept
   - Decoupling of the input and output clock system possible
• Scan rate conversion
   - Simple 100/120 Hz interlaced scan conversion (e.g. AABB, AA*B*B)
   - Simple progressive scan conversion (e.g. AA*)
• Flexible digital vertical expansion of the output signal (1.0, ... [1/32] ... , 2.0)
• Flexible output sync controller
   - Flexible positioning of the output signal
   - Flexible programming of the output sync raster
• Signal manipulations
   - Insertion of coloured background
   - Vertical and/or horizontal windowing with four different speed factors
   - Flash generation
   - Still field
   - Support of split screen applications
   - Multiple picture display - Tuner scan (4 and 16 times for 4:3, 12 times for 16:9 tubes)
   - Support of multi picture display with PIP or front-end processor with integrated scaler
      (e.g. 9 times display of PIP pictures, picture tracking, random pictures, still-in-moving picture, moving-in-still picture)
• I²C-bus control (400 kHz)
• P-MQFP-64 package
• 3.3 V ± 5% supply voltage
