COLORADO SPRINGS, Colo., 7 Aug. 2006. Leaders of Aeroflex Colorado Springs have begun production of their radiation-hardened QML Q and V UT200SpWPHY01 SpaceWire physical layer transceiver.
SpaceWire is a standard governing serial communication between satellite components. The protocol is self-managing and provides a high speed, low power serial interface while offering a simple user interface. The standard supports data rates of 2 to 400 megabits per second over 10 meters of cable.
The UT200SpWPHY01 supports data rates as fast as 200 megabits per second with data/strobe transmit skew less than 400 picoseconds. The UT200SpWPHY01 has a 3.3-volt power supply and cold spare on LVDS pins. ESD performance of LVDS inputs/outputs is greater than 8000 volts HMB.
The UT200SpWPHY01 physical layer transceiver (the LVDS physical layer for Aeroflex's SpaceWire protocol handler) takes care of critical timing issues associated with the SpaceWire data/strobe encoding scheme.
The UT200SpWPHY01 can withstand 300 kilorads of total-dose radiation, upsetting charge particle strikes to 40 MeV-cm2/mg and is single-event latchup immune to greater than 100 MeV-cm2/mg. It comes in a 28-pin flatpack (0.14 in2 ceramic body) and is QML Q and V compliant.
"Aeroflex Colorado Springs saw the benefits of the SpaceWire standard used in numerous European satellites and announced our SpaceWire product family in November 2005," says Anthony Jordan, director-standard products for Aeroflex, which is in Colorado Springs, Colo. "The benefits are straightforward. SpaceWire is a simple protocol, a simple user interface (FIFO) with high data rates and low power using LVDS as the physical layer."
Originally developed by the European Space Community (document ECSS-E-50-12A), SpaceWire marries IEEE-1355 with an LVDS physical layer.
The UT200SpWPHY01 physical layer transceiver is QML Q and V qualified. Prototypes and production units are available now. The UT200SpWPY01 is $1,069 in lots of 100. For more information contact Aeroflex Colorado Springs online at www.aeroflex.com/SpaceWire.
