| 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 Rev.: C Date: 02-07-08 CVH-731/751 Straight Multiplication HCMOS VCXO Frequency Range: 50Mhz to 180Mhz Temperature Range: (Option M) (Option X) Storage: 0C to +70C (standard) -20C to +70C -40C to +85C -45C to 120C Frequency Stability: (ppm) VS Temp.(ref. to +25C) 15, 20, 25, 50, 100 Max VS Supply Chage 5% 5ppm Max VS Load Chage 10% 3ppm Max Input Voltage: (731) (751) 3.3V 0.3V 5.0V 0.5V 25~60mA (Freq.
