SDA9400中文资料MICRONAS数据手册PDF规格书

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.

特性 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)
