CVH-731/751
Straight Multiplication
HCMOS VCXO
Model CVH-731/751 is a 50Mhz to 180Mhz HCMOS Voltage Controlled
Crystal Oscillator. Designed using straight multiplication operating at 3.3Vdc
or 5.0Vdc and -40 to +85C operating temperature.. This design provides cost
advantage over the HFF mesa design and superior performance over PLL
designs. This VCXO is also available in 3.3Vdc and 5.0Vdc Clock Oscillator
versions.
Applications include Broad band Networks, SONET/SDH/DWD, ATM,
Network/switch and Base Stations
