Product Details

Description



Features:

· Video encoding
· Image compression technique: Compression in conformance with the ISO/IEC 13818-2 (MPEG2 video) and ISO/ IEC 11172-2 (MPEG1 video) standards
· Generation of image sizes for the DVD video recording standards from ITU-R BT.656 (D1 parallel input) conforming signals
· Functions for conversion of horizontal and vertical resolutions.
· Special quantization processing and filtering (time, horizontal, and vertical axes)
· Audio encoding
· Encoding techniques: Dolby Digital and linear PCM
· Sampling frequency: 48 kHz
· Number of channels: 2 channels (left and right)
· Digital input interface: One system (supports both master and slave mode operation)
· External components
· External host for initialization and user-specific settings, and buffer memories (One 32-bit 64M SDRAM or two 16)
· Power supply system: Two supply voltages: 3.3 V (I/O supply voltage and internal PLL circuit supply voltage), 1.8 V (internal circuit supply voltage)


Application

· Used in the encoder block in AV recording equipment that uses the MPEG2 technique, such as DVD recorders.

Storage temperature Tstg -40 to +125 °C

Note) 1. The absolute maximum ratings are limit values for stresses applied to the chip so that the chip will not be destroyed. Operation is not guaranteed within these ranges.
2. All of the 3.3 V VDD pins, 1.8 V VDD pins, and VSS pins must be connected externally to the 3.3 V power supply, 1.8 V power supply, and ground, respectively.
3. Connect bypass capacitors (at least 0.1 mF) between the 3.3 V VDD and VSS pins, between the 1.8 V VDD and VSS pins, and between the AVDD and VSS pins.
4. The power supply voltages must be applied in the following order: first apply the 3.3 V system level (3.3V-VDD, AVDD), and then apply the 1.8 V system level (1.8V-VDD).
When removing power from this IC, first remove the 1.8 V system level (1.8V-VDD) and then remove the 3.3 V system level (3.3V-VDD, AVDD).


Description

The MN85571AC is an audio/video encoder that performs video compression in conformance with the ISO/IEC 13818-2 (MPEG2 video) and ISO/IEC 11172-2 (MPEG1 video) standards and audio compression in conformance with the Dolby Digital* system. MN85571AC also can multiplex the compressed audio and video signals.
