Parameter
Electrical Specifications:
Model 109
Surface Mount OCXO
Features:
• Frequency Range: 5 to 50 MHz
• Micro Package Size
• Low Cost Options Available
• Able to Withstand 240°C Reflow
• Electronic Frequency Adjust Standard
The Model 109 is a micro size OCXO with big performance. Less than .5 cubic inches, it is
capable of covering a wide range of performance through the use of precision AT crystals and
newer SC cut crystals. The 109 series is able to meet the requirements of GSM systems,
Private Branch Exchange (PBX), SONET and SDH 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.
