The aLFA-C is a sophisticated interfacing ASIC designed for use in space-borne infrared readout integrated circuits (ROICs) and other types of image sensors. It serves to replace much of the traditional infrastructure found in classic front-end electronics, thereby streamlining operations and improving efficiency. Notably, the device can function on a minimal single unregulated power supply, facilitated by on-chip Low Dropout regulators (LDOs) and Regulators. The aLFA-C's architecture allows it to run on either an external clock or a crystal oscillator interface, contributing to versatile deployment scenarios. With SpaceWire as its interface for external communication, the device can integrate smoothly into a range of systems. The aLFA-C also features a fully programmable sequencer to manage the ROIC, offering eight levels of nesting and dynamic reprogrammability. In terms of adaptability, the aLFA-C provides 32 programmable level single-ended digital outputs that can be transformed into 16 differential outputs using CMOS, LVDS, or CML formats. Additionally, it includes 16 programmable threshold single-ended digital inputs, which can be configured into LVDS or CML inputs. With capabilities for resistance, voltage, and current measurement, and a wide operating temperature range from 35K to 330K, the aLFA-C is robust and suited for demanding environments.
The FaintStar Sensor-on-a-Chip is an advanced technology designed for space applications requiring precision and reliability. It integrates all necessary components onto a single chip, facilitating ease of use and superior performance in star tracking and navigation scenarios. The sensor is characterized by a 1020 x 1020 pixel array with a 10-micron pixel pitch, making it suitable for high-resolution applications. Built for resilience in space conditions, the FaintStar sensor is flight-proven with a Technology Readiness Level 9 (TRL9), indicating a high level of maturity and reliability. It includes 'light-to-centroids' image processing capabilities that allow for accurate position tracking and navigation determinations. Moreover, its SpaceWire LVDS command/data interface supports high-speed data communication, ensuring efficiency during space missions. Featuring a radiation-tolerant design, the FaintStar sensor can withstand the challenging space environment, including Total Ionizing Dose (TiD) and proton radiation. It complies with ITAR-free and ESCC standards, such as 2269000-evaluated and 9020 flight model procurement, ensuring it meets the rigorous requirements for international use in aerospace applications.
The ELFIS2 Image Sensor is a high-performance visible light imager designed to withstand harsh environments. Its standout feature is the robust radiation hardness, making it ideal for applications requiring extreme reliability under radiation exposure. The design ensures resistance against total ionizing dose (TID), single event latch-up (SEL), and single event upset (SEU), confirming its suitability for demanding operational environments. The sensor boasts a true High Dynamic Range (HDR) capability, allowing it to capture a wide spectrum of illumination levels without compromising on image quality. This functionality is complemented by a Motion Artifact Free (MAF) global shutter, ensuring sharp and distortion-free images even in high-speed scenarios. Furthermore, the back-side illumination (BSI) design enhances light absorption, improving image performance in low-light conditions. With an emphasis on durability and versatility, the ELFIS2 offers users a reliable imaging solution that meets the requirements of specialized scientific and industrial applications. It stands out not only for its technical specifications but also for its ability to drive new possibilities in imaging applications from space exploration to cutting-edge microscopy.
