The FR-4 base of the Model 110 assures reliable solder joints without thermal expansion
problems. The Model 110 is capable of covering a wide range of performance through the use
of precision AT crystals and newer SC cut crystals. The 110 series is able to meet the require-
ments 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.
