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.
