We have already received requirements for commercial space applications of RPXO (which we can not respond to yet) and that has further exposed the potential value of our proposition to our customers who manufacture the various instruments for NASA and other first tier space payload contractors. Sensors, controllers and communication modules are the examples of such usage. There are a number of applications for our proposed RPXO in avionics and jet engine controllers as well as other military driven system application. The jet engine market segment is a new and growing one which intends to eliminate complex, heavy and unreliable wire harnesses in the present aircrafts. Low flicker noise of SiGe HBT makes the ASIC suitable for low phase noise and low jitter applications such as instrumentation, radar, optical transceivers and high speed network applications. The proposed RPXO is intended for very demanding and high radiation missions such as Europa EJSM (JEO & JGO), Mars Sample Return, Titan, missions to comets, Juno, space station, and GPM. The compelling features and performance of the proposed RPXO makes it highly suitable for most scientific and commercial space missions that require high speed data transfer link. This device could operate during take-off, interplanetary travel, orbit entry as well as landing of the probe. RPXO can be used in processor modules, DSP, servo control, receivers, transmitters, & sensors, auxiliary memory modules, where clock signal stability (temperature, shock, vibration, etc.) and integrity (signal to noise, phase noise and phase jitter) is critical.
