SCI1920A
ROIC, 1920 x 1080, 15UM
The SCI1920A is a Readout Integrated Circuit (ROIC) for detector arrays with a resolution of 1920 x 1080 pixels and a pitch of 15 µm. It provides up to 120 frames per sec through 8 single-ended analog output channels. The pixel is based on a Capacitance Trans Impedance Amplifier (CTIA), supporting snapshot shutter exposure and low noise correlated double sampling readout. Many different operating modes and conditions can be programmed via serial interface. Important features that can be changed are: full well capacity (FWC); snapshot shutter mode, i.e. Integrate Then Read (ITR), Integrate While Read (IWR) and Non-Destructive Read (NDR), and column amplifier gain. All biases are generated on-chip and derived from a bandgap reference. These biases can be programmed to optimize power dissipation and output voltage swing for each operating mode. The exposure time is defined by the pulse length of the external control signal “exp”. Readout of Regions of Interest (ROI) with a center coinciding with the center of the entire active array is supported. The ROI size is controlled by the pulse length of the readout control signals “line” and “frame”. The ROIC supports readout of detectors of both polarities but is optimized for P diodes on N material. The minimum integration time is 1 usec. The shortest detectable pulse length is 100 nsec.
