oGeneral Description
.cThe OV6620 (color) and OV6120 (black and white) CMOS Im-
age sensors are single-chip video/imaging camera devices
designed to provide a high level of functionality in a single,
Usmall-footprint package. Both devices incorporate a 352 x 288
image array capable of operating up to 60 frames per second
t4image capture. Proprietary sensor technology utilizes ad-
vanced algorithms to cancel Fixed Pattern Noise (FPN), elim-
inate smearing, and drastically reduce blooming. All needed
n Frame exposure/line exposure option
n 5-Volt operation, low power dissipation
– < 80 mW active power
– < 10 µA in power-save mode
n Gamma correction (0.45/0.55/1.00)
n I2C programmable (400 kb/s):
– color saturation, brightness, contrast, white balance,
exposure time, gain
camera functions including exposure control, gamma, gain,
white balance, color matrix, windowing, and more, are pro-
grammable through an I2C interface. Both devices can be pro-
grammed to provide image output in either 8-bit or 16-bit
digital formats.
Applications include: Video Conferencing, Video Phone, Vid-
eo Mail, Still Image, and PC Multimedia.

Notes:
1. Zoom Video Port format output signal includes:
VSYNC: Vertical sync pulse.
HREF: Horizontal valid data output window.
PCLK: Pixel clock used to clock valid data and CHSYNC into Zoom V Port. Default frequency is 8.86MHz when use
17.73MHz as system clock. Rising edge of PCLK is used to clock the 16 Bit data.
Y[7:0]: 8 Bit luminance data bus.
UV[7:0]: 8 Bit chrominance data bus.
