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.

■ Fully programmable independent H and V

scaling with derating

■ ITU-R BT.656-4 YUV (YCbCr) 4:2:2, RGB 565,

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.

RGB 444 output formats

■ 8-bit parallel video interface, horizontal and

vertical syncs, 80 MHz (max) clock (VS6725)

■ MIPI CSI-2 interface option (VS6735)

■ Two-wire serial control interface

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.

■ On-chip PLL, 6 to 27 MHz clock input

■ Analog power supply, from 2.4 V to 3.05 V

■ Separate I/O power supply, 1.8 V or 2.8 V

levels

This complete camera module is ready to connect

to camera enabled baseband processors, back-

end IC devices or PDA engines.

■ Integrated power management with power

switch, automatic power-on reset and power-

safe pins
