We offer Consulting Services in the following areas:
Provide assistance for creation and evaluation of timebase / crystal oscillator specifications to ensure that the clients system has a signal source fit for purpose.
Help clients create appropriate screening procedures for various timebases/oscillators.
Deliver troubleshooting support to fix client system issues resulting from timebase / crystal oscillator defects, such as microjumps, poor phase noise, excessive Allan deviation/variance, temperature stability non compliance, excessive aging, shock and vibration effects, etc.
Create timebase / crystal oscillator design for clients that wish to implement their own embeddable time base such as, XO, VCXO, TCXO, and OCXO’s
Test and Automation
Design and provide customized testing solutions for client applications
Design and implement environmental testing (temperature, aging, etc)
Design production test fixturing and software for evaluation of electrical parameters such as, waveform capture/analysis, power, current, voltage, temperature, frequency, etc.
RF Circuit Design/PCB Layout
Provide RF circuit design for client applications such as crystal oscillators, Phase Locked Loops (PLL), multipliers, dividers, mixers, down converters, etc.
Create PCB designs for the above RF applications to minimize noise, and maximize isolation.
Ceramic Substrate/Package Design
Create customized solutions for clients requiring ceramic substrates and/or multilayer ceramic packages.
Recommend appropriate ceramic material based on clients specific needs (alumina, aluminum nitride, etc)
Design appropriate package (potted versus hermetic seal, surface mount versus pinned device, etc), based on applications environmental requirements (temp, humidly, shock/vibration, power dissipation)
Design Microcontroller and unique ancillary hardware circuitry to meet the clients needs.
Create firmware/software design to provide automation and/or human interface as specified by client
Utilize multicore microcontrollers to create designs that perform more tasks of interest in a smaller footprint
General Programming and Coding
Provide programming services for custom applications in several languages such as, Visual Basic, Visual Basic.Net, C, C++, Spin, as well as legacy languages such as Python, Fortran, HP Basic, etc.
Worthy of notation:
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:
ER&D offers consulting in XO, VCXO, OCXO, TCXO, VCTXO, DOCXO and a variety of other subject matters.
If you have any questions or would like more information on our consulting services, feel free to contact us.
We thrive on making the seemingly impossible, possible.
** 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.
