We have a very extensive resume' and knowledge base in the area of XO, VCXO, OCXO, TCXO, VCTXO, DOCXO, and the groundbreaking new technology called the ANNCXO (Artificial Neural Network Compensated Crystal Oscillator) ________________________________________________________________________________ **What is ANNCXO? ANNCXO is fully detailed in patent application number US 13/570,563 by inventor John Esterline and can be found on Google Patents at: http://www.google.com/patents/WO2013023068A1?cl=en _________________________________________________________________________________ ER&D offers consulting in XO, VCXO, OCXO, TCXO, VCTXO, DOCXO and a variety of other subject matters. _________________________________________________________________________________ ** Brief Summary of ANNCXO from IEEE Explore: Temperature Compensated Crystal Oscillators (TCXO) are widely used and well known frequency control products. Their performance has improved over the decades with the advent of newer and improved technologies. Evolution of the TCXO from resistor thermistor networks to modern polynomial generators has pushed TCXO temperature stabilities to nearly +/-100ppb deviation over the industrial temperature range of -40 to +85°C. Even with these great advances, users always need tighter stabilities. This paper focuses on a new temperature compensation technique for crystal oscillators. Through the use of an Artificial Neural Network (ANN), temperature compensation of AT cut crystal oscillators can be achieved with better than +/-10ppb stability over the industrial temperature range (-40 to +85 °C). This is more than a 10 fold improvement over state of the art polynomial function generator compensation.

Micro Jump / Phase Jump Screening

Micro jumps are an oscillator phenomenon where the frequency of the oscillator changes suddenly. These events are often random and non repeatable. Also referred to as phase jumps, phase bursts, or phase pops the nature of the micro jump can cause system related problems especially in phase locked applications.
