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.
