epc902/3/4/5 CCD Line Sensors

ESPROS' epc90x series high-performance CCD line sensors are embedded in a CMOS framework, making them solid-state CCD/CMOS imagers. The series is a derivative of the epc901 line imager chip, offering a higher speed and higher sensitivity with one line of 128 px, 256 px, or 512 px. The imagers can store up to four frames total in the frame store for ultra-high-speed image acquisition (fast acquisition/slow read-out).

The imagers a high-performance video amplifier (single-ended/differential) analog output for a very high SNR, allowing the user to select the interface. The acquisition of the image is automatically controlled by a hardware control signal. Once the acquisition is completed, the imagers set a ready signal. The transmission of the frame 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 number of read clock edges.

The devices offer various configuration options including gain of the read-out stage selectable of 1, 2, or 4, transmission direction left to right and right to left, single- or multi-frame acquisition, clearing of stored frames, periodic flushing of the pixel array to avoid blooming.
