What is a TCXO?
The output signal from a temperature sensor is used to generate a correction voltage via a compensation network. The correction voltage is applied to the varactor in the VCXO. The capacitance variations compensate for the crystal's frequency vs.temperature characteristics.

Package Structure	Features
a.H Type	• The thermal paths of both quartz and IC are the same, easy to get sync and precise compensated frequency. • Strong package structure to resist the thermal during SMT process. • Easy to achieve smaller size than 2016
b.Double Tape	• The thermal paths of both quartz and IC are quite different, hard to get sync and precise compensated frequency. • Poor package structure, high risk to separate after heating process.
c.All-in-One Type	• The thermal paths of both quartz and IC are not different, easy to get sync and precise compensated frequency. • Strong package structure to resist the thermal during SMT process. • Hard to achieve smaller size than 2016.
