Recent Trends in High Reliability Timing and Frequency Control Devices for Extreme Environment Applications

Abstract

Performance requirements for higher reliability extreme environment timing and Frequency control (TF) components have continued to evolve in the recent years. Bulk of this demand has been focused on specific performance attributes governed by system applications. Enhanced performance requirement has become the mainstream of requirements where SWaP (size, weight and power) improvement is interleaved with other critical parameters such as temperature range, frequency tolerance and long-term effects and in some cases the output spectral purity. Trendlines set by customer demand continues to be the main guide for more efficient solutions. Frequency Management International (FMI) has been in the forefront of advancing the performance attributes for Hi-Rel extreme environment components. We continue to proactively respond to the pressing needs and challenges for robust frequency control components that operate under extreme environmental conditions including extreme temperatures ranging from -200ºC to + 500ºC. The material in this writeup covers the more recent performance achievements tied to specific products and form-factors for high temperature applications.
