IBIS4-6600

The IBIS4-6600 is a solid state CMOS image sensor that integrates the functionality of complete analog image acquisition, digitizer and digital signal processing system on a single chip. The image sensor compromises a 6.6 MPixel resolution with 2210x3002 active pixels. The image size is fully programmable to user-defined  windows of interest. The pixels are on a 3.5 m pitch. The sensor is available in a Monochrome version or Bayer (RGB) patterned color filter array.

User programmable row and column start/stop positions allow windowing down to 2x1 pixel window for digital zoom. Sub sampling reduces resolution while maintaining the constant field of view. The analog video output of the pixel array is processed by an on-chip analog signal pipeline. Double Sampling (DS) eliminates the fixed pattern noise. The programmable gain and offset amplifier maps the signal swing to the ADC input range. A 10-bit ADC converts the analog data to a 10-bit digital word stream. The sensor uses a 3-wire Serial-Parallel (SPI) interface. It operates with a single 2.5V power supply and requires only one master clock for operation up to 40 MHz. It is housed in a 68-pin ceramic LCC package.

The IBIS4-6600 is designed taking into consideration interfacing requirements to standard video encoders. In addition to the 10-bit pixel data stream, the sensor outputs the valid frame, line and pixel sync signals needed for encoding.

This datasheet allows the user to develop a camera system based on the described timing and interfacing.
