The aLFA-C ASIC product serves as a highly programmable interface for space-borne infrared read-out ICs and other imaging sensors, designed to replace much of the necessary infrastructure found in traditional front-end electronics. This versatile ASIC can operate on a single, unregulated supply owing to its on-chip LDOs and regulators, and supports connectivity through a SpaceWire interface.
The device is equipped with a fully programmable sequencer interfacing with the read-out ICs, capable of handling 8 levels of nesting and allowing reprogramming on the fly. The ASIC also supports 32 programmable single-ended digital outputs that can be combined to form 16 differential outputs in various signal formats like CMOS, LVDS, or CML, enhancing integration flexibility.
For precision and adaptability, the aLFA-C includes a robust analog acquisition system consisting of 36 channels with differential/single-ended analog inputs and 16-bit ADCs. These components ensure high fidelity data acquisition and conversion, crucial in specialized use-cases. Additional features like resistance, voltage, and current measurement capabilities, as well as tolerance to radiation-induced events, further underline its suitability for complex space applications, maintaining full functionality across extreme operational temperatures from 35K to 330K.
