May 2002 LM9648 Color CMOS Image Sensor SXGA 18 FPS General Description Applications The LM9648 is a high performance, low power, 1/2" SX GA CMOS Active Pixel Sensor capable of capturing color still or motion images and converting them to a digital data stream. f f f f Mega-pixel class 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 Video and snapshot 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 Dual Mode Camera Digital Still Camera Security Camera Machine Vision Key Specifications Array Format Total: 1032 x 1312 Active: 1032 x 1288 Effective Image Area Total: 6.30mm x 7.83mm Active: 6.27mm x 7.81mm Optical Format 1/2" Pixel Size 6.0µm x 6.0µm Video Outputs 8 & 10 Bit Digital Frame Rate 18 frames per second Dynamic Range 57 dB Shutter Rolling reset FPN 0.5% PRMU 1.7% Sensitivity 2.5 volts/lux.s Fill Factor 49% Color Mosaic Bayer pattern Package 48 LCC Single Supply 3.0V +/- 10% Power Consumption 150mW Operating Temp -10o C to 50 oC Overall Chip Block Diagram sclk sda Register Bank I2 C Compatible Serial I/F Row Address Decoder POR pwd mclk Power Control clk gen snapshot Master Sensor Controller extsync +/- ch0 +/- ch1 MUX +/- ch2 +/- ch3 2002 National Semiconductor Corporation 10 bit A/D Digital V ideo Framer Horizontal Register Column CDS resetb Black Level Compensation APS Array sadr d[9:0] pclk hsync vsync www.national.com LM9648 Color CMOS Image Sensor SXGA 18 FPS ADVANCE INFORMATION Item Description Part Number LM9648 LM9648 SXGA, 18 frames per second, color CMOS image sensor.
