INTRODUCTION

The SX5437M21X-X0B0 is fully functional camera module with a built-in lens. A low-noise low-power color
CMOS image sensor, S5K437CX03 and an image signal processor, S5C7323X produce high-quality digital video
output including CCIR656 format with maximum 30 frames per second for full frame readout. With SAMSUNG

0.35µm CMOS image sensor process technology which is dedicated to higher sensitivity and lower-dark level
compared to standard CMOS process, and on-chip CDS and 10-bit column ADC circuit embedded, the CMOS
image sensor provides high signal-to-noise ratio with low power consumption. This compact camera system
consists of an image sensor, a signal processor and some passive components packed with IR-cut filter and lens
units. The system works with 2.8V single power supply and a clock. All the functions are controlled with control
register setting through the standard 2-wire serial interface.
