Electrical Specifications:
Model 107
Low Cost OCXO
Features:
• Frequency Range: 15 to 55 MHz
• Able to Meet Stratum 3
Performance
• Low Cost, High Performance
• Small Size - Only 1.02" x 1.42" x .50"
• Squarewave Output
The Model 107 OCXO provides Stratum 3 perfor-
mance in a package similar to a TCXO. Requiring
about 1 watt of power when stabilized, it can
provide temperature stabilities of less than 5 x 10-8.
The Model 107 comes with a small footprint of
1.02" x 1.42" x .50", and is perfect for Telecom-
munication and Instrumentation Applications.
