IQXT-311 Datasheet, PDF (1/2 Pages) IQD Frequency Products Ltd – TCXO Specification

ISSUE 1; January 2016
Description
The IQXT-311 delivers exceptional phase noise and jitter
performance, and enhanced frequency versus temperature
stability. The single chip oscillator with its analogue
compensation circuit is capable of sub 0.1ppm frequency
stability over an extended temperature range and RMS phase
jitter down to 0.13ps for IEEE1588 and SyncE applications.
FEATURES:
RMS phase jitter down to 0.13ps.
Phase noise < ‐160dBc/Hz noise floor.
Voltage Control and T‐sense options available.
APPLICATIONS:
Positioning
