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.
