TCXO Specification
IQXT-316
ISSUE 1; January 2016
Outline (mm)
Description
The IQXT-316 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-316 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.

Output Control
Tri-State Mode:
Logic '0' (20%Vs max) to pad 6 disables the oscillator output,
the output goes to a high impedance state.
Logic '1' (60%Vs min) or no connection to pad 6 enables the
oscillator output.
