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
