LM9647 Color CMOS Image Sensor VGA 68 FPS
General Description
Applications
The LM9647 is a high performance, low power, 1/4" VGA CMOS
Active Pixel Sensor capable of capturing color still or motion
images and converting them to a digital data stream.

Excellent image quality is achieved by integrating a high performance analog signal processor comprising of a high speed 10
bit A/D convertor, fixed pattern noise elimination circuits and
separate color gain amplifiers . The offset and black level can be
automatically adjusted on chip using a full loop black level compensation circuit.
Furthermore, a programmable smart timing and control circuit
allowing the user maximum flexibility in adjusting integration
time, active window size, gain, frame rate. Various control, timing and power modes are also provided.
Features
f Master and slave mode operation
f Progressive scan read out with horizontal and vertical flip
f Programmable Exposure:
- Master clock divider
- Inter row delay
- Inter frame delay
- Partial frame integration
f Four channels of digitally programmable analog gain
f Full automatic servo loop for black level & offset adjustment
on each gain channel
f Horizontal & vertical sub-sampling (2:1 & 4:2) with averaging
f Windowing
f Programmable pixel clock, inter-frame and inter-line delays
f I2 C compatible serial control interface
f Power on reset & power down mode
