Weighing in at less than 15 grams and less than two thirds of a cubic inch, the Model 108 is

capable of covering a wide range of performance through the use of precision AT crystals and

newer SC cut crystals. The 108 series is able to meet the requirements of GSM systems,

Private Branch Exchange (PBX) and Central Office Switch (COS) applications. Its size and

performance also make it ideal for Microwave and Synthesizer applications that require more

economy while maintaining a high level of performance.
