EPC901 EVALUATION KIT V1

General Description 

The epc901 is a high-performance CCD line sensor capable of storing a total of 4 frames in the frame store elements for ultra high-speed image acquisition. The acquisition of the image is controlled by a control signal SHUTTER. The epc901 flags when a frame is ready for read-out by asserting the DATA_RDY signal. The transmission of the frame over the video amplifier is controlled by the external control signal READ. When a read-out is initiated by a pulse on the READ signal, it is sampled by a CDS stage. After a fixed delay the frame can be shifted out through the video amplifier by applying the appropriate amount of read clock edges. 

The device offers various configuration options: 

■ Gain of the read-out stage selectable of 1, 2 or 4 

■ Transmission direction left to right and right to left 

■ Region of interest (ROI) center region (pixel 256 to 767) 

■ Binning of 2 or 4 pixels to reduce transmission time and noise 

■ Single- or multi-frame acquisition 

■ Clearing of frames stored and periodic flushing of pixel array to avoid blooming
