The MAX9530 is a quad-channel video decoder and audio codec for security applications. The part is specially designed to serve as the analog video front-end in multichannel DVRs (digital video recorders) and multicamera systems. The architecture supports byte- or frame-interleaved digital video output for direct connection to Maxim’s own H.264 codec family (i.e., MG3500* and later generations). The on-chip DDR2 memory controller enables output of frame-synchronized digital video from up to four asynchronous analog video inputs. The use of external memory is optional. Without any external memory, bypass mode provides for output of up to four separate channels of asynchronous video data in BT.656 digital component format. Excellent video quality and noise immunity are achieved with the use of differential input mode, integrated automatic video EQ, and the industry's best specifications for interchannel crosstalk.
