Maxim's 4-channel video decoder chip can be directly connected to its H.264 series processor
Located on November 1, 2010, it has widen the solution series of digital video signal paths, and the US-letter integrated product company (NASDAQ code: MXIM) launched MAX9530: analog video conversion and a 4 The channel is simulated to the digital front end to compress the audio signal required by the digital format. The on-chip integration memory controller supports multiple output formats, including direct connection to the Maxim's series of processors optimized H.264 format. This saves expensive FPGA or interface logic solutions needed.
When using Maxim's MG3500 H.264 video processor, the MAX9530 reduces system BOM costs while providing excellent system compressed video quality of more than $ 1. In the MAX9530, it is possible to excellent video quality, competitive cost, and ending the product to the new generation of the product to market advantages in the cost of the Multicamera Safety Recorder.
Conference on the fierce price goal of the security recorder
In a video security market, a large-scale deployment may involve an analog CCTV camera and microphone, each person needs to simulate digital compression, recording, transmission, and IP networks for digital compression, recording, transmission, and IP networks. In order to meet the fierce price goals of this market, the system designer needs a solution to the H.264 video processor cost-effective solution for connecting a variety of video and audio channels.
Normally, the designer needs an H.264 video decoder for the video processor of the FPGA and the interface. The cost per person is around 5 US dollars, and the FPGA can add hundreds of large-scale deployment of dollars and total installation costs.
Maxim's terminal to the terminal digital video compression solution
The purpose of the MAX9530 is to eliminate the requirements directly connected to MG3500 H.264 video processors and other interfaces that Maxim. It performs all digital conversions required for 4 analog video and audio input channels.
When paired with the MG3500, the MAX9530 provides a complete video / audio signal path of "simulating to compressed numbers". This provides system designers with dual-chip, terminal to terminal solutions, greatly simplifies design and reduces the cost of safe recorders.
Direct connection becomes possible, through the integrated memory controller of the MAX9530, it optimizes the combination into a single data format 4 channels of H.264 compressed streams. Unlike other 4-channel decoders depending on the compression engine to recover all 4 channels, the MAX9530 automatically performs this feature to save the performance of the key video processors in advance.
Unparalleled video quality
The analog to digital conversion (video decoding and audio conversion) is an analog video / audio input in any system of the signal path, and uses the first step in digitization. Video decoders and audio ADCs are therefore critical to determining video and audio quality for compression and downstream deep processing levels.
The MAX9530 provides unparalleled video quality, which is attributed to its 54MHz 10-bit ADC, differential input, video equalizer, and industry-leading inter-channel crosstalk ("60 decibels). Differential simulation input improved high-intensive digital board Immunization capabilities, simplify the layout and design of the system. In addition, its unique 4-channel digital EQ function recovers the loss of high-frequency per video input signal, maintains the integrity of long cable applications.
