The aLFA-C product is an advanced interfacing ASIC designed for space applications, specifically for infrared readout ICs (ROICs) and other image sensors. It integrates much of the typical front-end electronics infrastructure in a single solution, offering versatility through features such as operation on a single unregulated supply using onboard LDOs and regulators, and compatibility with external clocks or crystal oscillators. Communication with external devices is achieved via a SpaceWire interface, and a programmable sequencer with 8 levels of nesting enhances the control towards the ROIC. Capable of handling 32 programmable digital outputs, the aLFA-C also allows the customization of input thresholds and output formats, supporting CMOS, LVDS, and CML. Its analog acquisition system includes 32 signal channels plus 4 reference channels, each with differential or single-ended input capability and 16-bit ADC resolution. The ADCs are equipped with features like calibration and post-correction, supporting various configurations for enhanced speed and performance. Additionally, the aLFA-C provides several programmable voltage sources and current outputs, accompanied by measurement capabilities for resistance, voltage, and current, making it extremely flexible for a wide range of applications. Its design is robust against radiation, exhibiting tolerance against TID, SEU, and SEL, and operates efficiently in temperatures from 35K to 330K, making it ideal for the harsh environments of space.
The FaintStar star sensor-on-a-chip device is a crucial component for precise space navigation and tracking. It features a resolution of 1020 x 1020 pixels, equipped with a 10μm pitch, facilitating high-precision detection of star patterns. The sensor incorporates a 12-bit A-to-D converter, which enhances the dynamic range and accuracy of the imaging process. Designed with advanced 'light-to-centroids' image processing capabilities, the FaintStar offers rapid and precise calculation of star positions, critical for navigation systems requiring real-time data handling. The space-proven status (TRL9) underscores its reliability and effectiveness in operational space conditions. Additionally, the sensor supports a SpaceWire LVDS command/data interface, allowing for efficient data communication. Engineered for durability, the FaintStar is radiation-tolerant, handling the harsh conditions encountered in space environments. It is compliant with ESCC 2269000 evaluation and ESCC 9020 flight model procurement, indicating its adherence to space hardware standards and ensuring its readiness for mission-critical applications.
ELFIS2 is a versatile image sensor designed to cope with challenging environments, with its high reliance on radiation-hardened features. This sensor is characterized by its true high dynamic range (HDR) capabilities, making it optimal for applications requiring accurate light detection across a broad range of intensities. The ELFIS2 features motion artifact-free (MAF) operation, a critical attribute for high-fidelity imaging. Built with a global shutter and back-side illumination (BSI), the sensor ensures all pixels capture light simultaneously, which is vital for sharp images devoid of motion blur. The BSI technology further enhances its sensitivity by allowing more light to reach the photodiode, a crucial feature for low-light conditions or fast imaging demands. With its SEL/SEU radiation-hardened design, the ELFIS2 is tailored for environments exposed to high radiation levels, like space or certain industrial settings. This resiliency, coupled with its innovative design, makes ELFIS2 suitable for complex imaging tasks, capturing high-quality images without compromising performance.
