VCXO Module IC with Built-in Varicap
OVERVIEW
The 5076 series are miniature VCXO ICs that provide a wide frequency pulling range, even when using minia-
ture crystal units for which a wide pulling range is difficult to provide. They employ a recently developed vari-
cap diode fabrication process that provides a wide frequency pulling range and good linearity without any
external components. Also, they employ a regulated voltage drive oscillator circuit that significantly reduces
current consumption, crystal current, and oscillation characteristics supply voltage dependency. The 5076
series are ideal for miniature, wide pulling range, low power consumption, VCXO modules.

*1. The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscil-
lation frequency range 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.

FUNCTIONAL DESCRIPTION
Oscillation Start-up Detector Function
The devices also feature an oscillation start-up detector circuit. This circuit functions to disable the outputs
until the oscillation starts. This prevents unstable oscillator output at oscillator start-up when power is applied.
