Back illuminated digital output CMOS image sensor

Capella are large area UV-NIR, radiation tolerant, CMOS image sensors designed for space applications.

Key benefits include low-light, 45Ke and 80Ke full well capacity (FWC) sensor variants, back-illumination, with on chip analogue to digital conversion (ADC), and is therefore easy-to-use.

Designed as a general purpose imager for space applications, Capella combines low readout noise and on-chip analogue-to-digital conversion to give excellent image quality.

Pixel read timing is set by an on-chip sequencer to simplify use and to reduce pin count.

A column parallel ADC is used to quantise each row of pixels in turn and is controlled by its own sequencer. Resolution can be set from 8 to 14 bits.

Four low-voltage differential signalling (LVDS) channels output the image data and are controlled by the readout sequencer to scan along each row in turn. Two LVDS synchronisation channels allow accurate data sampling.

All configuration settings are programmed over an SPI. This includes shutter mode, ADC resolution and bias current values. Different package options are available.
