Teledyne e2v Releases 4MP BSI Rad-Hard Sensor

Teledyne e2v has released a new image sensor, the CIS120, for harsh environments such as space applications. Samples have been available since February 2019 along with a full test and demonstration system.

Key specifications of the CIS120 include a resolution of 2048 x 2048 and BSI 10µm square pixels with a QE of 90% at 550 nm (typical). The sensor offers both a rolling shutter mode with a frame rate of 30 fps (8 bit) and a global shutter mode with a frame rate of 20 fps (12 bit).

Key features include:

• Good latch-up immunity and high SEU threshold by design and is resistant to ionising radiation by process choice
• Pixel read timing is set by an on-chip sequencer to simplify use and to reduce pin count
• A column parallel ADC is controlled by its own sequencer
• Resolution can be set anywhere from 8 to 14 bits
• Four LVDS channels output the image data and are controlled by the readout sequencer to scan along each row in turn.
• All configuration settings are programmed over an SPI. This includes shutter mode, ADC resolution and bias current values
• Package options include ceramic PGA and metal and ceramic three-side butting designs for use in mosaic focal planes
• CIS120 is stitched, so other sizes are possible from 2048 × 1024, up to 2048 × 8192 pixels, without the cost of new masks as well as other customer-specific requirements such as anti-reflective coatings
• An increased charge capacity of 100 ke– is possible by a metal pattern change
