LM9647  Product Folder

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.

• Master and slave mode operation
• Progressive scan read out with horizontal and vertical flip
• Programmable Exposure:
  • Master clock divider
  • Inter row delay
  • Inter frame delay
  • Partial frame integration
• Four channels of digitally programmable analog gain
• Full automatic servo loop for black level & offset adjustment on each gain channel
• Horizontal & vertical sub-sampling (2:1 & 4:2) with averaging
• Windowing
• Programmable pixel clock, inter-frame and inter-line delays
• I™C compatible serial control interface
• Power on reset & power down mode
