Unfortunately, we have to cancel this year's European Frequency Control Congress (EFCC) on November 21, 2017 in Munich due to a low number of registered participants. We thank you for your understanding and hope to invite you to one of our next events soon.

2nd European Frequency Control Congress & Exhibition

The European Frequency Control Congress & Exhibition (EFCC) is an international conference and exhibition, providing information on recent advances and trends of scientific research and industrial development in the fields of Frequency and Time.

Conference

The conference provides an insight into the basics of Frequency Control Products, the state of research but mostly the state of industrialization and application.

There will be a series of tutorials covering a wide range of related topics. The tutorials include both the fundamental topics of Frequency and Timing at a level suitable for practitioners new to the field, and more advanced and specialized topics related to specific areas. As such, the tutorials aim to provide useful knowledge to the beginners in the community, as well as those with extensive experience.

The lectures will be presented in German or English language.

Exhibition

The European Frequency Control Congress & Exhibition 2017 also offers an exhibition, which is open to all conference participants and provides space for technical exchange.

An optimal environment to present your products - share your experience and start the dialogue with colleagues and potential customers.

Quartz Crystals - always good for a surprise.

Lecturer: Bernd Neubig / Axtal GmbH & Co. KG german language Lecture in German

Schwingquarze und Keramikresonatoren sind wichtige Taktgeber in unzähligen Mikrokontrollern und Mikroprozessoren. Datenblätter und Applikationsberichte enthalten oft keine, meistens unzureichende und manchmal sogar falsche Hinweise zur Dimensionierung und Beschaltung der On‐Chip‐Oszillatorstufe.

Zuverlässiger Betrieb von Schwingquarzen erfordert:

  • Sicheres Anschwingen auch im Wort‐Case‐Fall
  • Berücksichtigung eines Worst‐Case Quarzes bzw. Resonators
  • Abschätzung der Chargenstreuung der Eigenschaften des On‐Chip‐Oszillator
  • Berücksichtigung nichtlinearer Eigenschaften von Quarz (Drive Level Dependence, DLD) und Oszillator (Kleinsignalverstärkung, Amplitudenbegrenzung)
  • Kenntnis des Verhaltens über Temperatur von Quarz (Frequenzstabilität, TK‐Dips, Widerstand, Aktivitätsdips) und Oszillatorstufe (Verstärkung/Steilheit über Temperatur)
  • Optimaler Oszillator – Arbeitspunkt
  • Optimale Quarzbelastung (HF‐Strom)
  • korrekte Lastkapazität, passend zur Arbeitsfrequenztoleranz

Insight views into quartz crystal and oscillator production.

Lecturer: Gerd Reinhold / WDI AG german language Lecture in German

OCXOs versus TCXOs - what are the differences?

Lecturer: Harald Rudolph / KVG Quartz Crystal Technology GmbH german language Lecture in German

As soon as the limited frequency stability of a simple XO – also called clock oscillator – is not satisfying for a specific application the design engineer has to decide whether he could use a Temperature Compensated Crystal Oscillator (TCXO) or he need to use an Oven Controlled Crystal Oscillator (OCXO).

On one hand the frequency stability of TCXOs and even of MEMS oscillators is improving continuously; on the other hand the size of OCXOs is shrinking and the power consumption is decreasing what makes it hard to decide what is the right choice.

The aim of this lecture is:

  • to explain the different technical approaches for TCXOs and OCXOs
  • to explain the different characteristics, advantages and disadvantages of TCXOs and OCXOs
  • to depict the technical limits of TCXOs and OCXOs

Lowest Oscillators Phase Noise - where are the limits?

Lecturer: Henry Halang, Bernd Neubig / AXTAL GmbH & Co. KG english language Lecture in English

Over the last decades the phase noise of crystal and SAW oscillators has steadily improved to lower and lower noise levels. Where are the physical and practical limitations? This will be covered under several aspects

  • Resonator: AT vs. SC-cut, SAW resonator, frequency, overtone, impact of resonator Q, Comparison or manufacturers
  • Oscillator: Impact of oscillator circuit, Loaded Q, Multi-resonator oscillators, improvement by crystal filter, frequency multiplication, Phase-locked loop. Aging of phase noise?
  • Phase noise measurement: Limitation by thermal noise floor, noise corruption in cross-correlation measurements. Comparison of test instruments
  • Environment: Impact of mechanical micro-vibration, influence of thermal fluctuations

Memristors - Future technology of frequency control components?

Lecturer: Dipl.-Ing. Marian Trinkel / 3I Ingenieurbüro german language Lecture in German

Memristoren bilden eine sehr junge Klasse elektronischer Bauelemente, die in der Schaltungspraxis noch weitgehend unbekannt ist. Erste praktische Schaltelemente entstanden vor zirka zehn Jahren von HP (2008). Die besondere Eigenschaft des an sich passiven Bauelement Memristor ist, sein Frequenzverhalten - und dass zwei feste elektrische Widerstandswerte sich ausbilden können, wobei diese eine Abhängig vom vorherigen Schaltzustand aufzeigt. Mit dieser Eigenschaft ist es möglich, dass ein Memristor als nichtflüchtiger Speiche, als Basis für neuronale Netze zur Darstellung komplexer Rechenoperationen, aber auch als Oszillatoren Verwendung findet.

Die Literatur zum diesem Thema ist umfänglich und weit gestreut. Das Autorenteam hat den Stand der Technik, die Literatur systematisch gesammelt, gesichtet, eingeordnet und strukturiert, so das ein Kompendium zum Thema entstand und hier als kurzer Auszug wiedergegeben wird.

Zusammenfassend kann gesagt werden, der Memristor hat eine interessante n-polare elektrische Eigenschaft, mit der Chance einer interessanten Zukunft in unterschiedliche Anwendungen zu erhalten, wobei die sogenannte "Killerapplikation" noch nicht gefunden ist.

Oscillators with quartz and silicon resonators. An Overview.

Lecturer: Dr. Klaus Barenthin / SE Spezial-Electronic GmbH german language Lecture in German

Nahezu alle elektronischen Oszillatoren für Timing-Anwendungen bestehen aus zwei Komponenten, einem frequenzbestimmenden Resonator und einem CMOS-IC zur Anregung des Resonators und zur Ausgabe des Taktsignals. Nachdem sich quarzbasierende Produkte bereits sehr erfolgreich etabliert hatten, wurde die Palette der Resonatoren vor etwa 10 Jahren noch einmal um Schwingungserzeuger aus Silizium erweitert. Unter der Bezeichnung „MEMS-Resonator“ haben auch letztere inzwischen einen hohen Bekanntheitsgrad erreicht.

Der Vortrag befasst sich mit dem Einfluss der derzeit verfügbaren quarz- und silizium-basierenden Resonatoren auf wichtige Eigenschaften elektronischer Oszillatoren. An Hand ausgewählter Timing-Produkte der Marktführer Seiko Epson Corp. und SiTime Corp. wird außerdem gezeigt, wie mit der jeweiligen Technologie aktuell Oszillatoren mit Spitzenparametern gefertigt werden können. Der Inhalt des Vortrags wird abgerundet durch einige Informationen zur Programmierung von Oszillatoren, die inzwischen wahlweise vom Hersteller, Distributor oder Anwender vorgenommen werden kann.
