[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
