5037 series
2.5V LVDS Output Oscillator ICs
OVERVIEW
The 5037 series are 2.5V operation, LVDS output oscillator ICs. They support 80MHz to 400MHz 3rd over-
tone oscillation and 80MHz to 600MHz fundamental oscillation. The 5037 series can be used to construct
high-frequency LVDS output oscillators.

*1. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscilla-
tor 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.
