NIRCA - Control and acquisition for FPA imaging

2015.05.21

1. Reduce system design complexity and time.2. Reduce detector size - Cryogenic operation allows for integration

into the detector head dewar.3. Reduce power consumption.

Prototype available today.

NIRCA Benefits:

1. Integration of FPA system components on one chip.2. Generation of up to 40 digital signals for ROIC control.3. Regulated power for the ROIC.4. Analog and digital signal acquisition.5. 16 x DACs for biasing and voltage references.6. Custom readout schemes – reconfiguration on runtime.
