Clock Module - häufig gestellte Fragen

This application note introduces our range of advanced clock modules which provide electrical timing functionality for distributed network systems. These units primarily revolve around the 1PPS (pulse per second) timing synchronisation signal produced by a GPS receiver which is derived from transmitted timing information received from GPS satellite systems ......


Quarzlagerung

A quartz crystal unit includes a small strip or disk of quartz that is processed to an exact size and thickness dependent on the customer specified resonating frequency. The quartz is plated with conducting electrodes and mounted in a hermetically sealed protective enclosure ......


Jitter und Phasenrauschen

An introduction to noise and jitter. A measurement of the performance of a frequency system is its stability, i.e. the level of fluctuations in frequency over a suitable measurement. The goal is to keep these fluctuations to a minimum; however noise and jitter are unavoidable within a system and can negatively affect the performance ......


Kristallresonatoren

The importance of quartz crystal resonators in electronics results from their extremely high Q, relatively small size and excellent temperature stability. A quartz crystal resonator uses the piezoelectric properties of quartz. The direct piezoelectric effect refers to the electric polarisation of certain materials brought about by the application of mechanical stress ......


Pluto Temperaturkompensation

Die Temperatur ist ein wichtiger Faktor bei der Angabe der Stabilität der Kristall-Oszillatoren. Mit dem Ausgleich für die Auswirkungen der Temperatur auf die Frequenz der Schwingung der Kristall, ein TCXO Expozition kann bis zu 100-mal bessere Stabilität über den Temperaturbereich bieten, als ein vergleichbarer unkompensierter Oszillator ......


Haltbarkeit quarzbasierender Frequenzprodukte

The purpose of this brief is to detail what can happen to a quartz based timing device while stored on the shelf and when this could cause a problem ......


Quarzalterung

Ageing of a quartz crystal results in a small change of frequency overtime and this effect may have to be taken into account by the customer when designing their circuit depending upon the overall specification that needs to be achieved. There are two main causes of ageing in quartz crystals, one due to mass-transfer and the other due to stress ......

Band & Rollenangaben

Here you can find information about IQD Tape and Reel information and Statek Tape and Reel packaging information. All dimensions are based on international standard EIA-481-D ......

Zeiteinhaltung

Since its introduction the 32.768kHz miniature watch crystal has become the most popular time keeping reference ever. This application note is intended to give some guidance as to the use of quartz crystals in time keeping applications ......
