It has one sink pad to receive the MIPI CSI-2 stream (usually from a MIPI CSI-2 camera sensor). It has four source pads, corresponding to the four MIPI CSI-2 demuxed virtual -channel outputs. Multpiple source pads can be enabled to independently +channel outputs. Multiple source pads can be enabled to independently stream from multiple virtual channels.
