CF5073 series

VCXO Module ICs with Built-in Varicap

OVERVIEW

The CF5073 series are VCXO ICs with built-in varicap diode. They use a recently developed negative-resis-

tance switching oscillation circuit, at oscillation startup and during normal oscillation, for both good oscilla-

tion startup characteristics and wide pullrange. Furthermore, it employs a CMOS process varicap diode, and

also features all the necessary VCXO structure circuit components on a single chip, forming a VCXO module

with just the connection of an external crystal.

1. The typical oscillation frequency is the oscillation frequency criteria for use when selecting the device version. Note that the oscillation

characteristics and pullability vary with the crystal used and the mounting conditions. Even for the same frequency, the optimal version can vary

with crystal characteristics, so careful evaluation should be exercised when selecting the device version.

2. These versions are produced after receiving a purchase order. Please ask our Sales & Marketing section for further detail.
