CF5037 series 2.5V LVDS Output Oscillator ICs .. OVERVIEW The CF5037 series are 2.5V operation, LVDS output oscillator ICs. They support 80MHz to 250MHz 3rd overtone oscillation and 80MHz to 700MHz fundamental oscillation. The CF5037 series can be used to construct high-frequency LVDS output oscillators. Features 2.375 to 3.6V operating supply voltage range Operating frequency range (varies with version) - 80MHz to 700MHz fundamental oscillation - 80MHz to 250MHz 3rd overtone oscillation - 40 to 85°C operating temperature range LVDS output Standby function - Outputs are high impedance when OE is LOW.

The remended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of ponents must be carefully evaluated. - 2.
