Description
The VS6725/VS6735 is a CMOS color digital
camera featuring low size and low power
consumption for mobile applications. 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.
