Model 111
Miniature HF OCXO
CRYSTALS
Features:
• Frequency Range up to 120 MHz
• Stratum 3 Performance
• Surface Mount or Thru Hole Option
• Miniature Package
• Wide Operating Temperature Range
The Model 111 is a DIP Packaged OCXO that is
available over a wide range of stabilities and
temperatures. It is ideal for communications as a
Stratum 3 reference or as a local oscillator for
higher frequency multiplication. The Model 111 is
made possible by adjustments made in packaging
high precision crystals into smaller foot prints.
