INTRODUCTION : THE FORDAHL GROUP The Fordahl Group, founded in 1981, has grown to become one of a few truly global frequency control products manufacturer in the world. Located in Switzerland, Fordahl SA is the corporate headquarters for the group as well as the main production facility. Situated in the heartland of the time and frequency region of central Europe, the availability of skilled labour has allowed Fordahl to specialise in miniature ultra stable oscillators mostly dedicated to the needs of the telecommunication market. Dedication to supplying quality products has reflected in Fordahl's ISO 9001:2000 certification. Efficiency and time management has led to the implementation of all procedures on Intranet, focusing on accessibility and userfriendliness. RoHS compliance of all our products has been effective since June 2005 already. The emphasis in research and design continues to be driven by the need to reduce size and power requirements and at the same time increase performance levels at lower cost. For this reason the ‘S’ series of SMD devices includes every class of crystal oscillator from simple clocks (CXO) up to tight voltage controlled temperature compensated oscillators (VC-TCXO). The Fordahl Group has actively worked to become a true global player focusing on a wide range of products and services. Proximity to customers and complete traceability when projects move across international boundaries are essential ingredients for a continued growth in our industry. The Fordahl Offices: Fordahl France SA, located in Créteil, south of Paris is responsible for our sales onto the French market as well as for the sales of lower end device such as clock oscillators, simple crystals, etc… all around Europe Fordahl SA (UK), located in Southampton, England is the sales and logistics centre for the United Kingdom and Ireland as well as for the North of Europe. Fordahl Deutschland has the primary function to better serve and support the local market as well as Eastern Europe. This territory has become the cornerstone of several global telecommunication companies and CEM’s. Fordahl USA, Inc. is the main co-ordination centre for our North American operations, located near Atlanta. It is responsible for leading a team of independent representatives that provide technical and logistic support across the continent. Managing the flow of inter-continental opportunities makes this centre here instrumental for our future. The Fordahl Group has been working steadily towards fulfilling the needs of the market over the last 25 years. In the following pages, you will find a description of our standard generic products.
