4-channel video decoder and audio codec from Maxim for security applications

Maxim Integrated Products has introduced the MAX9530, a 4-channel analog-to-digital front-end IC for converting analog video and audio signals to the digital format required for compression. An on-chip memory controller is integrated to support a variety of output formats, including the optimal format for direct connection to Maxim's family of H.264 processors.

For interfacing multiple video and audio channels to an H.264 video processor designers opt for an FPGA to interface the video decoder with the H.264 video processor. Maxim says this FPGA option costs around five dollars apiece. Maxim suggests this device meets aggressive price targets for security DVRs and eliminate the interface requirement by directly connecting to Maxim's MG3500 and other H.264 video processors. It performs all the digital conversions required for up to 4 channels of analog video and audio input.

Maxim claims unlike other 4-channel decoders that rely on the compression engine to reformat all 4 channels separately for compression, the MAX9530 performs this function automatically in advance to preserve critical video processor performance.

The MAX9530 is designed to deliver high video quality due to its 54MHz 10-bit ADC, differential inputs, video equalizer, and interchannel crosstalk (> 60dB).

Operating temperature range: 0°C to +70°C

Package: 12mm x 12mm 196-pin CSBGA
