DATASHEET
Architecture
General Description
The OV528 Serial Bus Camera System performs as a
video camera or a JPEG compressed still camera and can
be attached to a wireless or PDA host. When it performs
as a video camera, the TFT-LCD panel of the host
operates as a viewfinder. Users can send out a snapshot
command from the host in order to capture a full
resolution single-frame still picture. The picture is then
compressed by the JPEG engine and transferred to the
host.
Functional Description
OV528, the Single Chip Camera-to-Serial Bridge, is a low-
cost, single-chip & low-powered solution for high-
resolution serial bus PDA/cellular phone camera
accessory applications. Along with OV76x0/OV66x0
CMOS VGA/CIF color digital CameraChips, OV528
comprises a low-cost, highly integrated serial camera
system. There is no additional DRAM required.
The OV528 system, as shown in Figure 1, consists of a
CameraChip, Program Memory and OV528 Serial Bridge.
Camera Sensors
The OV528 supports OmniVision OV76x0/ and OV66x0
CameraChips with an 8-bit YCbCr interface.

Program Memory
A program memory is required for the embedded MC to
respond to host commands correctly, as well as to store
all necessary parameters for adjusting
image/compression qualities. A serial type program
memory is required for OV528, while both serial and
parallel types of program memory can be adapted to
OV528-100.
The contents of the program memory can be updated on
the fly.
OV528 Serial Bridge
The OV528 Serial Bridge is a controller chip that can
transfer image data from CameraChips to wireless/PDA
hosts.
The OV528 takes 8-bit YCbCr 422 progressive video data
from an OV76x0/OV66x0 CameraChip. The camera
interface synchronizes with input video data and performs
down-sampling, clamping and windowing functions with
desired resolution, as well as color conversion that is
requested by the user through serial bus host commands.
The JPEG CODEC with variable quality settings can
achieve higher compression ratio & better image quality
for various image resolutions.
The Serial Camera Control Bus is used to achieve greater
flexibility in camera interface.
