5076 series

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.
