Abstract

The MIRAS space instrument under development by the European Space Agency will be used to measure ocean salinity and soil moisture of the Earth by listening to the Earth radiation at 1.4 GHz. The instrument is a microwave radiometer based on aperture synthesis technology: 84 antennae, divided over 3 arms, collect data which is then correlated in a central processing unit to simulate a single large antenna. Radiation data is digitized at the antennae. An optical harness distributes clocking data to the antennae to synchronize the digitizing of the data, and transports the captured binary data to the processing unit. Data from four antennae is grouped, resulting in a speed of 559.8 Mbps (16/20 encoding) per fiber. The optical harness is built using RoCC (Robust Communication Controller), a serializer/de-serializer/phase-recovery chipset being developed by Siemens (Herentals) in DMILL (Durci Mixte Isolant Logico Lineaire) technology for radiation hardened communication. The presentation gives an overview of the complete optical harness: fiber, transmitter and receiver, and focuses on technology choices made to realize the RoCC chipset. The chipset also accommodates other speeds, and can e.g. be used to realize fiber channel or gigabit ethernet using two fibers. Architectural details are provided.
