CF5036 series
2.5V LVPECL Output Oscillator ICs
OVERVIEW
The CF5036 series are 2.5V operation, differential PECL output oscillator ICs. They support 50MHz to
250MHz 3rd overtone oscillation and 50MHz to 700MHz fundamental oscillation. The devices are fabricated
using a proprietary BiCMOS process, enabling a high-frequency oscillator circuit and differential LVPECL
output buffer to be incorporated on a single chip. The CF5036 series can be used to construct high-frequency
PECL 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.
