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 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

- 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

Applications

f Security Camera
f Machine Vision
f Barcode Scanners
f Biometrics
