1 / 2 page  ©2002 National Semiconductor Corporation www.national.com ADVANCE INFORMATION LM9637 Monochrome CMOS Image Sensor VGA 68 FPS General Description 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. Excellent image quality is achieved by integrating a high perfor- mance 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 com- pensation 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, tim- ing 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 I2C compatible serial control interface f Power on reset & power down mode Applications f Security Camera f Machine Vision f Barcode Scanners f 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 3.89mm 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 -10oC to 50oC Overall Chip Block Diagram Column CDS Amp d[9:0] pclk hsync vsync 10 bit A/D snapshot extsync APS Array I2C Compatible Serial I/F Register Bank sclk sda sadr POR Power clk gen Control mclk pwd resetb Master Sensor Controller +/- Figure 1.
