The epc901 IC is a high-performance CCD line sensor with 1024 pixels. The monolithic integration of CCD pixels within a CMOS framework facilitates system integration and operation of this imager. The image acquisition is controlled by a simple shutter and a read clock signal. Data is output over an analog stage which allows either single-ended or differential output. The imager is highly configurable and includes internal CCD frame stores for ultra high-speed burst mode operation of 500 kfps.

Burst mode

The epc901 has an integrated CCD frame store that is used to increase frame rate up to 500 kfps for four consecutive images. The image information is stored in the charge domain to minimize noise. The frame store is organized as a FIFO. Thus, up to four images can be acquired in fast sequence without intermediate readout.

Configuration options

Various parameters and operation modes are user-configurable:

• Gain of the read-out stage selectable: 1, 2 or 4
• Transmission direction selectable
• Region of interest (ROI) centre region (pixel 256 to 767)
• Lateral binning of 2 or 4 pixels
• Single- or multi-frame acquisition
• Clearing of frames stored and periodic flushing of pixel array to avoid blooming
