CYIA2SC0300AA-BQE 1/3” VGA-Format CMOS Image Sensor Features VGA Resolution 1/3” Optical Format Automotive Grade device 120 db Dynamic Range 60 PIN CBGA Low power dissipation 1 Sensor Architecture Functional Description Cypress IM103 is Automotive grade CMOS Image Sensor with high dynamic range (120 db). IM103 is built with Autobrite® technology useful for Automotive Vision Systems which produce crisp clear video in visible and near IR wavelengths. Device can be used for Lane departure working, Night Vision, Adaptive Cruise control, driver drowsiness etc. The diagram in Figure 1 shows the major functional blocks of the imager. These blocks include: Image sensor array Row control circuitry Column sense circuitry Analog-to-digital converters Timing and control logic Program registers Digital-output shift registers Sensor array: The sensor array consists of an optically active 482 row X 642 column matrix, with 18 additional dark columns on right side of the array (the array is described more fully in section 3). Each sensing element (pixel) is 8 µm X 8 µm in size. Timing and control circuitry: The sensor uses two clocks (data strobe or DSTR, and system clock or SCLK). Data strobe controls the timing of the output shift registers, while SCLK controls exposure and data conversion timing. Clocking details are given in section 5. Column circuitry: The column circuitry includes a column amplifier (with correlated double sampling [CDS] capability) and a ...
