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
