TCXO Specification

IQXT-318

ISSUE 1; January 2016

Description

Outline (mm)

The IQXT-318 uses ASIC technology and is designed to meet

the short and medium term stability requirements of packet

network synchronisation for Small Cells. The oscillator has low

jitter to meet network interface requirements (e.g. 10GE) and

low phase noise to meet radio interface requirements of LTE-A

(TS 36.104) and WCDMA (TS 25.104) transceivers. The

IQXT-318 is the ideal choice for Small Cell synchronisation

requirements.

FEATURES:

Patented ‘varactor linearisation’ removes the effects of tilt

when using voltage control.

HCMOS and Clipped Sinewave output options available.

LTE phase noise compliant.

Temperature sensor option.
