TCXO Specification

IQXT-315

ISSUE 1; January 2016

Description

Outline (mm)

The IQXT-315 uses ASIC technology to provide enhanced

frequency versus temperature stability. It also delivers to the

industry the lowest jitter achievable from an ultra-stable TCXO.

This allows the oscillator to be compliant with various

standards including GR-1244, GR-253, G.812, G.813, G.8262

and G.827x.

FEATURES:

RMS phase jitter down to 0.13ps.

Phase noise < 160dBc/Hz floor.

Excellent frequency stability.

APPLICATIONS:

Stratum 3 / IEEE 1588 / SyncE

SONET / SDH / WDM / OTN

Carrier Ethernet / Microwave

Backhaul / Transport Equipment

Standard Frequencies: 10.0MHz, 12.80MHz, 16.3840MHz,

19.440MHz, 20.0MHz, 20.480MHz, 24.5760MHz, 25.0MHz,

30.720MHz, 38.880MHz and 40.0MHz.

Example Phase Noise @ 20.0MHz
