CF5037 series

SEIKO NPC CORPORATION —1

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.

Recommended operating

*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.
