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 over-
tone oscillation and 80MHz to 700MHz fundamental oscillation. The CF5037 series can be used to construct
high-frequency LVDS output oscillators.

*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentica-
tion. 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 components must be carefully evaluated.
*2. Minimum output frequency: 80MHz
