Key highlights
A half-duplex transceiver with a single-point failure tolerant design and in-built health telemetry. The system is cold in transmit and receive, with optional hot redundancy in receive, and features serial communication interfaces using differential signaling (CAN, M-LVDS) and an ESA-approved ICD.
Main features:
- High performance MCU
- Health telemetry
- Serial communication interfaces using differential signaling (CAN, M-LVDS)
- Space grade connector to the backplane
- Channel coding: RS, BCH
- Tailoring ECSS/CCSDS
