FSA-FTx/A#
The following chapters provide the relevant technical information for sensor modules (FSM) with native MIPI CSI-2 data output.
A setup with single or multiple sensor modules consists of one to four FSMs, each with an appropriate sensor-specific FSA, and one FPA for the target processor board. Only FSA and FPA designs shown in this chapter are compatible with each other.
While the FRAMOS Sensor Modules (FSM) are designed for maximum efficiency, the FRAMOS Sensor Adapters (FSA) support all current sensors and their specific electronic requirements, from voltage rails to reference clock generation. The goal is to reduce noise and heat generation on the image sensor board by shifting these functions to the FSA. Additionally, users have the option to integrate this circuitry into their own processor board designs, aiming to reduce size and redundancy. All electrical references are created and provided on a per-project basis.
