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°C to +85°C 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: E Date: 11-Feb-10 Page 1 of 3 CRYSTEK CORPORATION 12730 Commonwealth Drive • Fort Myers, Florida 33913 Phone: 239-561-3311 • 800-237-3061 Fax: 239-561-1025 • www.crystek.com CVH-731/751 Straight Multiplication HCMOS VCXO Frequency Range: Temperature Range: (Option M) (Option X) Storage: Frequency Stability: (ppm) VS Temp.(ref. to +25°C) VS Supply Change ±5% VS Load Change ±10% Input Voltage: (731) (751) Input Current: Input Impedance: Control Voltage: (731) (751) Settability At Nominal: (731) (751) Output: Symmetry: (Option Y) Rise/Fall Time: Pullability APR: (ppm) Linearity: Logic: Load: Start-up Time: Modulation BW: Sub-harmonics: Phase Noise Typical: 10Hz 100Hz 1kHz 10kHz 100kHz Aging: 50MHz to 180MHz 0°C to +70°C (standard) -20°C to +70°C -40°C to +85°C -45°C to 120°C ±15, ±20, ±25, ±50, ±100 Max ±5ppm Max ±3ppm Max 3.3V ±0.3V 5.0V ±0.5V 25~60mA (Freq.
