CIS-125 Frame Grabber
HIGH-SPEED CONTROL & DATA ACQUISITION FOR TELEDYNE e2v CIS125
DEDICATED ELECTRONICS FOR HIGH-RESOLUTION TDI IMAGING
Sensor control, real-time acquisition and high-speed payload data handling in one integrated electronics architecture.
EMM’s HRT electronics provide the interface between the CIS125 focal plane and the spacecraft data system. The electronics handle camera configuration, payload control and image acquisition while transferring camera data to the OBC through dual 10 Gigabit Ethernet interface.
PURPOSE-BUILT FOR CIS125: Electronics tailored to the control and data-handling needs of Teledyne e2v’s TDI sensor.

PROCESSING CHAIN FOR CONTROL & DATA HANDLING The
ICPU combines sensor control and configuration functions with real-time image acquisition and a high-speed data interface to the spacecraft OBC. The focal plane is connected to the ICPU electronics via a flex PCB, providing both power distribution and high-speed data transmission. Camera configuration parameters are stored in non-volatile memory to ensure retention across power cycles.
