Features:
• Double Oven
• Small Size
• High Stability
• Electrical Frequency Adjust
• 5 to 15 MHz
The Model 115 is a high performance double oven
OCXO housed in a small package. The use of a 5 MHz
3rd overtone SC coldweld crystal provides for excellent
long term aging performance. Applications include
CDMA base station reference and Stratum II clock.
