Maxim's 4-channel video decoder SOC can be directly connected to the company's H.264 processor series, which reduces more than $ 1 per channel.
The SOC containing video decoders and audio codecs is available for security and automotive market Sunnyvale, CA. November 1, 2010. Maxim Integrated Products (NASDAQ: MXIM) Extension its digital video signal channel, the 4-channel mode / digital conversion front end MAX9530 can be converted to the digital format required for the analog video and audio signals into compression processing. In-chip integrated memory controller supports multiple output formats, including: direct connection to the Optimal format of the Maxim H.264 processor series. The device does not require a common expensive FPGA or interface logic circuit in a competitive scheme. When used in conjunction with Maxim's MG3500 H.264 video processor, the MAX9530 can provide excellent system video quality required for compression processing, and can reduce BOM cost more than $ 1 per channel. The MAX9530 is thus available for a new generation of multi-camera security DVR systems. Such applications require end-to-end single source scenarios with excellent video quality, competitive price and short listing time. The price goal of satisfying the safety DVR application In the video security market, large-scale systems often have hundreds of analog CCTV video camera and microphones, each device needs to be modest and subsequent digital compression, recording circuit connection, and pass through IP network transmission. In order to meet the positioning of this market, system designers need to adopt programs with high cost performance to achieve multiple video and audio channels and H.264 video processors. In general, designers need to use FPGA to connect video decoders and H.264 video processors. FPGA's single-chip price is approximately $ 5, which will increase hundreds of US dollars in installation costs for large-scale systems. Maxim's end-to-end solution for digital video compression applications The MAX9530 can be directly connected to the MAXIM's MG3500 and other H.264 video processors described above. The device can provide 4 channel analog video and audio input required for all digital conversion functions. When used in conjunction with the MG3500, the MAX9530 can provide complete "simulation to the compressed digital video / audio signal channel. This two-chip, end-to-end solution allows system designers to greatly simplify the design difficulty of safety DVR systems, reduce costs. The MAX9530 built-in memory controller enables direct connections to the video processor, which collects four channels of signals into data streams of single channel optimal format for H.264 compression processing. Unlike other 4-channel decoders depending on the compression engine, 4 channel data is differentially converted and compressed, and the MAX9530 will automatically complete the functionality to ensure the key performance of the video processor. Unparalleled video quality For any system that accepts analog video / audio input and digital processing, analog / digital conversion (video decoding, and audio conversion) is the first aspect of the signal path. The performance of the video decoder and audio ADC is critical to the video and audio quality of subsequent compression and processing links. The 54MHz 10-bit ADC, differential input, video equalizer, and industry-leading channels (>60dB) characteristics can provide unparalleled video quality. Differential simulation input can improve the noise suppression capability of large density digital board, simplify system layout and design. In addition, the unique 4-channel digital equalization function of the device can compensate for high frequency losses per channel input to ensure signal integrity in long distance cable applications.
