TCXO Specification

Part No. + Packaging:

LFTCXO070179Cutt

Description

The IQXT-274-6 employs an analogue IC for the oscillator and

temperature compensation. The crystal is surface mounted on

top of the ceramic IC carrier. The segregation of the crystal from

the oscillator further improves the reliability of the product.
