ADVANCE INFORMATION

LM9648 Color CMOS Image Sensor SXGA 18 FPS

General Description

The LM9648 is a high performance, low power, 1/2" SXGA
CMOS Active Pixel Sensor capable of capturing color still or
motion images and converting them to a digital data stream.

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

Applications

f Dual Mode Camera
f Digital Still Camera
f Security Camera
f Machine Vision
