It integrates a high-sensitivity pixel array, a digital image processor and camera control functions. The VS6725/VS6735 is capable of streaming UXGA video up to 15fps, with ITU-R BT.656-4 YUV 4:2:2 frame format or 30fps SVGA using analog binning. It supports 1.8 V/2.8 V digital interface and requires a 2.4 V to 3.05 V analog power supply. If required, the VS6725/VS6735 can operate as a 2.8 V single supply camera. The integrated PLL allows for low frequency system clock, and flexibility for successful EMC integration. This complete camera module is ready to connect to camera enabled baseband processors, backend IC devices or PDA engines.
