MAY 2002 LM9637 Monochrome CMOS Image Sensor VGA 68 FPS General Description Applications The LM9637 is a high performance, low power, 1/4" VGA CMOS Active Pixel Sensor capable of capturing monochrome still or motion images and converting them to a digital data stream. f f f f 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 a programmable gain amplifier. 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 Programmable gain amplifier 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 Security Camera Machine Vision Barcode Scanners Biometrics Key Specifications Array Format Total: 488 x 672 Active: 488 x 648 Effective Image Area Total: 2.93mm x 4.03mm Active: 2.93mm x 3.89 mm Optical Format 1/4" Pixel Size 6.0µm x 6.0µm Video Outputs 8 & 10 Bit Digital Frame Rate 68 frames per second Dynamic Range 57 dB Electronic Shutter Rolling Reset FPN 0.5% PRMU 1.7% Sensitivity 2.40 volts/lux.s Fill Factor 49% Micro Lens none Package 32 LCC Single Supply 3.0V +/-10% Power Consumption 130mW Operating Temp -10o C to 50 oC Overall Chip Block Diagram sclk sda Register Bank Row Address Decoder POR pwd mclk Power Control clk gen snapshot Master Sensor Controller extsync +/- Amp 10 bit A/D Digital Video Framer Horizontal Register Column CDS I2 C Compatible Serial I/F resetb Black Level Compensation APS Array sadr d[9:0] pclk hsync vsync Figure 1.
