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. |
